如何判断自己外网IP是否为真实公网IP

如何判断本地(路由器)分配的IP是否公网IP?

公网IP:全球唯一IP地址。(公网IP又分为静态公网IP和动态公网IP,如何分辨的话,进入路由器查看连接方式pppoe连接都是动态公网IP。)

有这么一种情况:拉的联通的带宽,分配的IP只能在联通内部访问,移动网络不能访问。这个IP最多只能算是“联通内的公网IP”,不是真的公网IP。

有多种方法都可以判断本地(路由)IP是否公网IP,以下一一罗列以供小伙伴们参考。

一,经验法:

1,一般电信adsl带宽在未升级大带宽前是(动态)公网IP。如果花费很少的钱给你升级为100M光纤上网,99.99%是内网IP,那0.01%是我还没有发现过案例。

2,代理网络运营商99.99%都是内网IP,如长城带宽、聚友E家等。

3,光纤上网的99.99%都是内网IP。很多人是100M独享上网,经测试有时候下载速度可以有10MBps(即100Mbps)。注意,这里说的下载速度。还有一个名词叫上行速度,请知晓

二,直观法:

1,10开头的IP都是内网IP。即10.0.0.0 到 10.255.255.255是内网IP。不少自家拉的带宽路由分配的都是10开头的IP,这类都是内网IP。

2,以下IP段的地址都是内网IP地址。

(1)10.0.0.0 到 10.255.255.255

(2)172.16.0.0 到172.31.255.255

(3)192.168.0.0 到192.168.255.255

(4)100开头的这个新的内网IP段

三,对比法:

1,登录自己的路由看自动分配的IP

2,登录http://www.ip138.com 网站看获取的IP地址

3,登录http://ip.qq.com 看获取的IP地址

4,登录万网http://www.net.cn/static/customercare/yourip.asp 查看获得的IP地址

(如万网获取IP是二个,则是IP经运营商转换的内网环境)

5,登录多个知名查IP网站查看IP地址结果对比,只要其中有一个结果IP不一致,即可说明是内网IP。注意,ip查询网站只是获得到你本地出口的IP,即使它是经过转发的IP。

四,询问法:

1,直接问自己的网络提供商,问他分配的IP是不是公网IP,跨网能不能访问到这个IP。如果网络运营提供商不肯定,或不能保证是公网IP,或说只提供你上网用,则意味着是内网IP。

五,亲测法:

1,本地开启远程桌面,并确保局域网内可以正常远程。然后在外网和跨网环境看看能不能通过IP进行访问。

2,本地部署一个网站应用或其他应用,并确保内网可以正常访问。然后在外网和跨网环境看看能不能通过IP访问。



如何申请公网ip?局域网IP怎样让外网访问实现内网穿透?

       如果自己想搭建一台网站服务器,或搭建服务器FTP/SVN/OA/ERP/数据库等用途时且需要提供外网连接访问场景,这此时候就需要公网IP。

      有公网IP的用户,用户可以直接通过公网IP连接。以下分享下申请公网IP的方法。

如何申请公网ip?

       现在互联网可以链接每台设备,但是如果要把自己的服务或信息提供给他人,就必须有公网IP,这个IP是可以自己申请使用的。对于公网IP地址的申请使用,其前提条件就是要向服务提供商租用服务器或空间,以便在服务器或空间上存储自己要对外发布的服务或数据。

    1,通过相关服务商购买申请。如购买使用带公网IP的空间。首先可以通过搜寻相应服务的提供商,会有大量的此类供应商,自己根据需要选择合适的服务提供商。选择好服务提供商后,即可以向其购买相关服务,此类服务包括服务器、空间、相关WEB服务及使用期限等等。购买相关服务或租用服务器后,即可向服务提供商申请独立IP地址,这个IP地址就是所谓的公网IP。在向服务提供商租用服务或服务器时要注意服务种类,比如服务器现在多数都是虚拟服务器,而不是实体的服务器;服务种类也包括很多,比如HTTP服务、数据存储服务等等,以及服务器操作系统类型,包括Linux 、Windows等,这些都可能是独立收费项,自己要根据自己需要进行选择性购买。

    2,自己接入宽带并申请公网IP。在接入宽带时,就要跟网络带宽商明确自己需要公网IP接入使用。自己接入家庭宽带不明确需要公网的话,默认都是给你内网IP的。一些地方可以免费提供公网IP。

 3,中途申请开通公网IP。一开始没有公网需求,但在使用过程中,发现需要了,这时可以尝试向对应的网络商申请开通公网IP。申请开通方式都是需要联系本地网络商具体负责人员,视情况而定。

4、郑州联通公网IP默认就有IPv6,没有IPv4(这里指动态公网IP,运营商会不定期更换,或者重启路由器拨号就会更换),IPv6环境也可以,但是工作的一个城市所使用的网络没有IPv6,于是打10010,客服听不懂什么是IP,让拨打96480。拨打96480后给小哥说要安装监控,话还没完,小哥就说是要公网IP吧,账号说下,报了账号,小哥说光猫和路由断电后重启就可以了。重启后,IPv4动态公网IP就有了。就是这么快,这么简单。

 

17个最佳免费匿名电子邮件帐户提供商

17 Best Free Anonymous Email Account Providers 2021

17个最佳免费匿名电子邮件帐户提供商2021

Do you want to send emails with full anonymity?

你想发送完全匿名的电子邮件吗?

If you use a standard email service like Gmail, you will not be anonymous. Sure, there are many email service providers that encrypt your messages — but that’s not the same thing as anonymity.

如果你使用像 Gmail 这样的标准电子邮件服务,你就不会是匿名的。当然,有很多电子邮件服务提供商为你的邮件加密,但这和匿名不是一回事。

In fact, Gmail still has access to your IP address, location, name, phone number, etc. They track your activity to show you ads, and your email account can be traced back to you.

事实上,Gmail 仍然可以访问你的 IP 地址、位置、姓名、电话号码等等。他们跟踪你的活动,向你展示广告,你的电子邮件帐户可以追踪到你。

It is possible to create an anonymous email account with Gmail — if you are smart about it. I will show you how to do so later in this article.

用 Gmail 创建一个匿名电子邮件账户是可能的,只要你够聪明。我将在本文后面向您展示如何做到这一点。

However, your best bet for sending and receiving anonymous emails is to sign up with a purely anonymous email account provider. These service providers don’t collect any personal information or track your data, so your account will never be traced back to you.

然而,你发送和接收匿名电子邮件的最佳选择是与一个纯粹的匿名电子邮件帐户提供商注册。这些服务提供商不会收集任何个人信息或者追踪你的数据,所以你的账户永远不会被追踪到你。

Today, I will be showing you the 17 best anonymous email account providers. All of them are free or offer a free plan.

今天,我将向你展示17个最好的匿名电子邮件帐户提供商。所有这些都是免费的或者提供免费的计划。

Let’s get into it!

让我们开始吧!

A Word About Staying Anonymous — Always Use a VPN

一句关于匿名的话ーー永远使用 VPN

I believe it is important to stress this — always use a VPN when using an anonymous email account. Alternatively, you can use the Tor browser (also known as the Onion browser), which scrambles your IP address.

我认为有必要强调这一点ーー在使用匿名电子邮件帐户时始终使用 VPN。或者,你也可以使用 Tor 浏览器(也称为洋葱浏览器) ,它会扰乱你的 IP 地址。

That way, nobody will be able to trace the email account back to you based on your IP address.

这样的话,就没有人能够根据你的 IP 地址追踪到你的电子邮件帐户了。

The 17 Best Free Anonymous Email Account Providers

17个最好的免费匿名电子邮件帐户提供商

1. ProtonMail

ProtonMail is my top recommendation for those looking for an anonymous email account they can use over and over again. Here is what makes ProtonMail so great:

ProtonMail 是我推荐给那些寻找一个可以反复使用的匿名电子邮件帐户的人的首选。以下是 ProtonMail 如此伟大的原因:

  • It does not require any personal information when signing up.
  • 注册时不需要任何个人信息。
  • Any user data it does have is protected by Swiss privacy laws, as ProtonMail is based in Switzerland, which is known for its strict privacy laws.
  • 它所拥有的任何用户数据都受到瑞士隐私法的保护,因为 ProtonMail 总部设在以严格的隐私法著称的瑞士。
  • It does not log your IP address. Theoretically, you don’t even need a VPN, though you should probably still use one for extra security.
  • 它不会记录你的 IP 地址。从理论上讲,你甚至不需要 VPN,尽管你可能仍然应该使用一个 VPN 来提供额外的安全性。
  • There is end-to-end encryption, which means that even ProtonMail can not access your messages.
  • 还有端对端加密邮箱,这意味着即使是 ProtonMail 也不能访问你的邮件。
  • It is open source, which means it is entirely free to use, and you can review the source code yourself.
  • 它是开源的,这意味着它是完全免费的,你可以自己查看源代码。
  • There is a mobile app, so you can use it on your phone.
  • 有一个移动应用,所以你可以在你的手机上使用它。

Proton has a calendar and cloud drive storage, which are also safe and secure.

质子有一个日历和云存储,这也是安全和安全的。

2. Guerilla Mail 游击队邮件

Guerilla Mail is the second-best email service provider for sending private, anonymous emails. You get a special email address that only you know — you will need to remember that email address to access your mail.

游击邮件是第二好的电子邮件服务提供商发送私人,匿名电子邮件。你得到了一个只有你自己知道的特殊邮箱地址ーー你需要记住这个邮箱地址才能访问你的邮箱。

There is no signup process, so anyone who knows the email address will be able to read the messages that get sent to it. There is no password, name, or personal information required to access the mail sent to that address — it is entirely anonymous.

没有注册过程,所以任何人谁知道电子邮件地址将能够阅读邮件发送到它。访问发送到该地址的邮件不需要密码、姓名或个人信息ーー它完全是匿名的。

Since the email address is only a string of letters with a random domain name, as you can see in the screenshot, it will be pretty hard for people to guess that email address.

由于电子邮件地址只是一串带有随机域名的字母,正如你在截图中看到的,人们很难猜到那个电子邮件地址。

I’m sure you’re wondering, “Well, people will know my email address if I use it to sign up on a website or to email someone! Once they know my address, will they be able to access my mail?”

我肯定你在想,“嗯,如果我用它注册一个网站或者给某人发邮件,人们会知道我的电子邮件地址!一旦他们知道了我的地址,他们还能查看我的邮件吗?”

The answer is no — nobody will know your email address. That’s because you will be given a second email address, which is basically a scrambled version of the first address.

答案是否定的ーー没有人会知道你的电子邮件地址。这是因为你会得到第二个电子邮件地址,基本上是第一个地址的混乱版本。

The second address is also a string of letters, numbers, and symbols. Even if someone has that second, scrambled email address because you gave it out or emailed them, it would be virtually impossible to guess the first email address (the one you use to view your inbox).

第二个地址也是一串字母、数字和符号。即使有人因为你泄露了邮件地址或者通过电子邮件发送了邮件而得到了第二个混乱的邮件地址,你也几乎不可能猜出第一个邮件地址(你用来查看收件箱的地址)。

Save your first email address in a safe place. I would suggest writing it down on a piece of paper and storing it somewhere secure.

将你的第一个电子邮件地址保存在一个安全的地方。我建议把它写在一张纸上,存放在安全的地方。

You can also memorize it, but it might be hard to memorize a string of random letters.

你也可以记住它,但是很难记住一串随机的字母。

If you store your unscrambled email address on your computer, there is the possibility that someone will be able to hack your computer and see it. If you write it on a physical piece of paper, you will be truly anonymous, and the email account won’t be able to be traced back to you (provided you are using Tor or a VPN).

如果你把你的电子邮件地址保存在你的电脑上,有可能有人会黑进你的电脑,看到它。如果你把它写在一张纸上,你就是真正的匿名者,而且电子邮件帐户不会被追踪到你(只要你使用 Tor 或者 VPN)。

In addition, all messages sent to your inbox will only stay there for one hour. It doesn’t matter whether you see them or not — they will disappear after an hour.

此外,所有发送到你的收件箱的邮件只会在那里停留一个小时。你是否看到它们并不重要ーー它们一个小时后就会消失。

That is a big downside — you will have to keep checking your inbox every hour. On the other hand, it also protects you in case anyone manages to figure out your address.

这是一个很大的缺点---- 你将不得不每小时检查你的收件箱。另一方面,如果有人发现了你的地址,它也能保护你。

You can change your first email address at any time — you can set your own string of letters. Also, you can send a Forget Me request to the server to delete your email address; otherwise, it will last forever.

你可以在任何时候更改你的第一个电子邮件地址ーー你可以设置你自己的字母串。此外,您还可以向服务器发送一个勿忘我请求以删除您的电子邮件地址; 否则,它将永远持续下去。

3. AnonAddy 匿名

AnonAddy is a free and entirely open source anonymous email account provider. You can create an unlimited number of anonymous email aliases for free.

是一个免费的完全开源的匿名电子邮件帐户提供商。你可以免费创建无限多的匿名邮件别名。

You might want several aliases for different purposes, such as when talking with different people, to make it harder for people to connect the dots and trace your activity back to you. It also helps confuse spammers.

你可能需要几个别名来达到不同的目的,比如和不同的人交谈时,这样人们就很难联系起来并追踪到你的活动。它也有助于迷惑垃圾邮件发送者。

Here’s how it works: First, you create your username and register it on the AnonAddy server.

它是这样工作的: 首先,你创建你的用户名并在 AnonAddy 服务器上注册它。

For example, if your username is JohnDoe, your domain will be This email address is being protected from spambots. You need JavaScript enabled to view it. or This email address is being protected from spambots. You need JavaScript enabled to view it.. Then, simply create any number of aliases and add them to the beginning of your domain to create a new email address.

例如,如果你的用户名是 JohnDoe,你的域名就是 JohnDoe。或 JohnDoe。匿名我。然后,只需创建任意数量的别名,并将它们添加到您的域名的开头,以创建一个新的电子邮件地址。

For example, you can create This email address is being protected from spambots. You need JavaScript enabled to view it. and This email address is being protected from spambots. You need JavaScript enabled to view it..

例如,你可以创建 Alias1@JohnDoe. anonaddy. com 和 Alias2@JohnDoe. anonaddy. com。

You don’t have to do anything in the dashboard. Just enter a random alias when filling out a subscription form, for example, and when you get an email sent to that address, it will automatically be registered in your dashboard.

你不需要在仪表盘上做任何事情。例如,在填写订阅表单时,只需输入一个随机的别名,当你收到一封发送到该地址的电子邮件时,它将自动注册到你的仪表盘上。

You can delete an alias at any time.

您可以随时删除别名。

4. Lavabit

Lavabit is a secure email service provider. In fact, when the US government ordered it to hand over its TLS encryption keys, it shut down its entire network instead of complying.

Lavabit 是一个安全的电子邮件服务提供商。事实上,当美国政府命令它交出 TLS 加密密钥时,它并没有遵守规定,而是关闭了整个网络。

That’s because Lavabit is truly committed to its mission of providing the world with access to secure email communication. After shutting down, it got right to work on DIME — Dark Internet Mail Environment, and it is now back up and running.

这是因为 Lavabit 真正致力于为世界提供安全的电子邮件通信的使命。在关闭之后,它可以正常工作在 DIME ー Dark Internet Mail Environment 上,现在已经恢复运行。

Since Lavabit uses end-to-end encryption, your messages are entirely safe.

因为 Lavabit 使用了端对端加密,所以你的信息是完全安全的。

There are three levels of encryption to choose from when using Lavabit:

在使用 Lavabit 时,有三种加密方式可供选择:

  • Trustful mode — you trust the server with your data
  • 信任模式——您将数据托付给服务器
  • Cautious mode — the server only stores encrypted data
  • 谨慎模式ー服务器只存储加密数据
  • Paranoid mode — the server never has access to your keys, even your encrypted keys
  • 偏执模式——服务器永远无法访问您的密钥,甚至您的加密密钥

Volcano is Lavabit’s free and open source client.

火山是 Lavabit 的免费和开源客户端。

5. TrashMail 垃圾邮件

Want a disposable, anonymous email address that forwards messages to your regular email address? You can use TrashMail to set up a fake email address that will last for a specified amount of time.

想要一个一次性的,匿名的电子邮件地址,转发信息到你的日常电子邮件地址?你可以使用垃圾邮件建立一个假的电子邮件地址,这个地址可以持续一段时间。

Give out this email address to stay anonymous. There is no dashboard — all mail is routed to your real email address.

给出这个电子邮件地址以保持匿名。没有仪表盘ー所有的邮件都被路由到你真正的电子邮件地址。

You don’t even need to create an account, though you can if you want to manage your email addresses.

你甚至不需要创建一个帐户,尽管你可以管理你的电子邮件地址。

To get started, create your custom email address on one of the domain options available. Enter the email address you want mail to be forwarded to and choose how long the disposable email address should last before being deleted.

首先,在可用的域选项之一上创建自定义电子邮件地址。输入您想要转发邮件的电子邮件地址,并选择在删除之前一次性电子邮件地址应该持续多长时间。

You can also add the TrashMail Chrome extension to your browser and use it from there.

你也可以把垃圾邮件扩展插件添加到你的浏览器中,然后在那里使用它。

6. Temp Mail 临时邮件

Temp Mail is another anonymous email account provider, designed for those looking for a temporary email address. I found it incredibly easy to use — it does not require you to sign up for an account.

临时邮件是另一个匿名电子邮件帐户提供商,专为那些寻找临时电子邮件地址。我发现它非常容易使用ーー它不需要你注册一个账户。

As soon as you land on the site, you will see your temporary email address, which is a random string of letters and numbers on a random domain.

一旦你登陆该网站,你会看到你的临时电子邮件地址,这是一个随机域名上的字母和数字的随机字符串。

Your inbox is available as soon as you land on the page. You can clear the inbox, delete your temporary email address, or edit your temporary email address to create a new one.

你的收件箱是可用的,只要你土地上的页面。您可以清除收件箱,删除您的临时电子邮件地址,或编辑您的临时电子邮件地址,以创建一个新的。

Unlike Guerilla Mail, it does not seem like you can compose and send an email from this temporary address. Instead, it is best used to sign up anonymously for forums or sites that require email registration.

不像游击邮件,它看起来不像你可以从这个临时地址撰写和发送电子邮件。相反,最好是匿名注册需要电子邮件注册的论坛或网站。

7. 10 Minute Mail 10分钟邮件

There are a number of 10 Minute Mail sites. I’m not sure if they are all owned by the same group or not.

有许多10分钟邮件网站。我不确定它们是否都属于同一个集团。

I’m going to go with 10MinuteMail.net, as that is the one I actually tested, and I verified that it works. I emailed the random address it gave me from my real email address — sure enough, the message arrived, and I was able to open it.

我打算用10minutemail.net ,因为这是我实际测试过的,并且我已经验证了它是有效的。我从我真实的电子邮件地址中随机发送了它给我的地址ーー果然,邮件到了,我打开了它。

The downside is that there are a lot of ads, and you may need to refresh the page to view new mail. However, it is free.

缺点是有很多广告,你可能需要刷新页面来查看新邮件。然而,它是免费的。

I can’t promise that other 10 Minute Mail sites work as they are supposed to.

我不能保证其他的10分钟邮件网站也能正常工作。

So, what’s the idea behind 10 Minute Mail? It’s simple, really: You get a temporary, anonymous email address that lasts for 10 minutes only.

那么,10分钟邮件背后的想法是什么呢?这很简单,真的: 你得到一个临时的匿名邮件地址,只持续10分钟。

You can use this email address to sign up for a site or forum that requires email registration or to get a free ebook without entering your real address. The email address consists of a random string of letters and numbers.

你可以使用这个电子邮件地址注册一个需要电子邮件注册的网站或论坛,或者在不输入你的真实地址的情况下获得一本免费的电子书。电子邮件地址由一串随机的字母和数字组成。

You can also give this email to someone to receive some information via email that you don’t want traced back to you.

你也可以把这封电子邮件发给别人,让他们通过电子邮件收到一些你不希望被追踪到你的信息。

After 10 minutes, your inbox and email address will expire.

10分钟后,你的收件箱和电子邮件地址将过期。

8. Mailfence

MailFence is based in Belgium, so it is protected by Belgian privacy laws, which are better than US privacy laws. As such, it can offer better privacy and anonymity than an American competitor.

MailFence 的总部设在比利时,因此它受到比利时隐私法的保护,这比美国的隐私法还要好。因此,它可以提供比美国竞争对手更好的隐私和匿名性。

For example, only a local judge can request personal information from it — it can’t be a judge from another country. Also, court orders for such things are very hard to obtain.

例如,只有当地法官才能向其索取个人信息ーー不能是外国法官。此外,法院对这类事情的命令也很难获得。

Even if such a court order was obtained, all emails are end to end encrypted, so even Mailfence can not read your emails.

即使获得了这样的法院命令,所有的电子邮件都是端对端加密的,所以即使是 Mailfence 也不能读取你的电子邮件。

Mailfence has worked hard to make sure it is using only top-notch security. A free plan is available, and 15 percent of the premium plans are donated to support privacy rights in Europe.

Mailfence 努力工作,以确保它只使用一流的安全性。一个免费的计划是可用的,并且15% 的保费计划是捐赠给支持欧洲的隐私权。

9. Tutanota 女名女子名

Tutanota lets you sign up for an account with your phone number and without any personal information, thus allowing you to create a truly anonymous email account. Not only that, but all emails have built-in encryption, so nobody can access the content of your emails.

让你注册一个帐户,用你的电话号码,没有任何个人信息,从而允许你创建一个真正的匿名电子邮件帐户。不仅如此,所有的电子邮件都有内置的加密,所以没有人可以访问你的电子邮件内容。

With the Tutanota mobile apps, you can send and manage your emails on your phone.

使用 Tutanota 手机应用程序,你可以在手机上发送和管理电子邮件。

A free account is available, but it is somewhat limited. For example, you only get 1 GB of storage space.

一个免费帐户是可用的,但是有一些限制。例如,你只有1gb 的存储空间。

10. Anonymous Email 匿名电子邮件

Anonymous Email is a cool little site that lets you send and receive emails anonymously. No registration is required — just visit the website and start using the service immediately.

匿名电子邮件是一个很酷的小网站,允许你匿名发送和接收电子邮件。不需要注册,只需访问网站并立即开始使用该服务。

To send an anonymous email, simply visit the site and edit the sender’s address in the first field. You can add any string of letters in front of This email address is being protected from spambots. You need JavaScript enabled to view it..

要发送匿名电子邮件,只需访问网站并在第一个字段中编辑发件人地址。你可以在 This email address is being protected from spambots. You need JavaScript enabled to view it. 前面添加任何字母串。

However, if you are using it for free, you can not receive replies anonymously. If you want to be able to get replies forwarded to your real email address without disclosing it, you have to sign up for the premium plan.

但是,如果你是免费使用的,你不能收到匿名回复。如果你想得到回复转发到你的真实电子邮件地址而不披露它,你必须注册保费计划。

So, if you are using it for free, leave the reply address blank, so nobody sees your real address. The recipient will see the email, but they won’t be able to respond.

所以,如果你是免费使用它,留下空白的回复地址,以便没有人看到你的真实地址。收件人会看到邮件,但他们不能回复。

11. 5Ymail

5Ymail is an excellent way to send emails anonymously. Simply go to the homepage, enter the recipient’s information, and compose your email!

5Ymail 是匿名发送邮件的绝佳方式。只需进入主页,输入收件人的信息,然后撰写您的电子邮件!

You can also enter your own email address, so you can get replies and create an account. Everything will still be 100 percent anonymous, but you will now be able to log in and manage your account, as well as receive notifications when you get new emails.

你也可以输入你自己的电子邮件地址,这样你就可以得到回复并创建一个帐户。一切仍然是100% 的匿名,但你现在可以登录和管理你的帐户,以及接收通知时,你收到新的电子邮件。

12. AnonEmail 匿名电子邮件

AnonEmail is one of the quickest ways to send an email anonymously. You can’t receive emails, however, — it’s a one-way thing.

匿名电子邮件是匿名发送电子邮件的最快方式之一。然而,你不能收到电子邮件,这是单向的。

Just visit the website, enter the recipient’s email address, create a subject line, write your email, fill out the captcha, and send your email!

只要访问网站,输入收件人的电子邮件地址,创建一个主题行,写你的电子邮件,填写验证码,并发送您的电子邮件!

13. myTrashMail.com 网址: mytrashmail

myTrashMail is a great service for those who want a temporary email address to receive emails anonymously. Whether you want to sign up for a website anonymously or receive some important information without it being traced back to you, you can do it with myTrashMail.

是一个很好的服务,对于那些想要一个临时的电子邮件地址来接收匿名的电子邮件。无论你是想匿名注册一个网站,还是想收到一些重要信息而不被追踪到你,你都可以使用 myTrashMail。

No account registration is required. When it says to enter your email, it means to enter the custom email address you want to create temporarily.

无须登记帐户。当它说输入你的电子邮件,它的意思是输入自定义的电子邮件地址,你想创建临时。

You can create a new email address using a random string of letters or a fake name — it doesn’t matter.

你可以用一串随机的字母或者一个假名字创建一个新的电子邮件地址ーー这不重要。

14. Craigslist 克雷格列表

I’m sure you’re wondering, “Craigslist? How is that an anonymous email provider?”

我肯定你在想,“ Craigslist? 那怎么会是一个匿名电子邮件提供商?”

Well, it’s not… but you can still use it to set up an anonymous email address. You see, when you create a listing on Craigslist, your real email address will be hidden on the listing, replaced with a random string of letters.

嗯,它不是... ... 但是你仍然可以用它设置一个匿名电子邮件地址。你看,当你在 Craigslist 上创建一个列表时,你真正的电子邮件地址将隐藏在列表中,并被随机的字母串替换。

Emails sent to that randomly generated address will be forwarded to your email account. That way, buyers can not see the personal information of sellers — it helps protect sellers from scammers.

电子邮件发送到随机产生的地址将被转发到您的电子邮件帐户。这样,买家就看不到卖家的个人信息ーー这有助于保护卖家免受骗子的欺骗。

So, to get an anonymous email account via Craigslist, all you have to do is create a list. It could be a simple posting pretending to sell an oven, for example.

所以,要想通过 Craigslist 获得一个匿名电子邮件帐户,你所要做的就是创建一个列表。例如,这可能是一个简单的假装卖烤箱的帖子。

Then, find that posting and click on the Reply button. Then, click on “Show Email.”

然后,找到发布,点击回复按钮。然后,点击“显示电子邮件。”

You will see a randomly generated email address. You can then give that email address to someone, so they can email you without them knowing your real email address.

你会看到一个随机生成的电子邮件地址。然后你可以把邮箱地址给别人,这样他们就可以在不知道你真实邮箱地址的情况下给你发邮件了。

This is a cool little hack that will usually work. There are more straightforward methods available, but it is still a valid option.

这是一个很酷的小黑客,通常会工作。还有更简单的方法可用,但它仍然是一个有效的选择。

15. TempInbox

TempInbox is a free and easy way to get a totally anonymous, private email address. You create your own email address — it can be any string of letters followed by @tempinbox.com.

TempInbox 是一个获得完全匿名的私人邮箱地址的免费而简单的方法。你可以创建自己的电子邮件地址ーー可以是任何一串字母,后面跟着@tempinbox. com。

16. Tempr.email 电子邮件

Tempr.email, like TempInbox, provides you with a customized temporary email address that is entirely anonymous. You can create a custom address followed by @tempr.email, @discard.email, discardmail.com, and a variety of other domains — you get to choose!

Email 和 TempInbox 一样,为您提供一个完全匿名的自定义临时电子邮件地址。您可以创建一个后跟@tempr 的自定义地址。电子邮件,@丢弃。电子邮件,discardmail. com,和其他各种各样的域名ーー你可以选择!

17. Gmail 谷歌邮箱

Finally, I’m going to show you how you can create an anonymous email address with Gmail and most other popular email providers (though it does depend on the provider and how much information they request from you).

最后,我将向您展示如何使用 Gmail 和大多数其他流行的电子邮件提供商创建一个匿名电子邮件地址(尽管这取决于提供商和他们向您索取多少信息)。

Here are the steps you need to take to create an anonymous account on Gmail:

以下是在 Gmail 上创建匿名账户的步骤:

  1. Make sure you always use a VPN or the Tor browser! That way, your IP address will not be exposed, and Gmail won’t be able to know where you are from.
  2. 确保你总是使用 VPN 或 Tor 浏览器!这样,你的 IP 地址就不会暴露,Gmail 也不会知道你从哪里来。
  3. Write a fake name. Use a name that sounds realistic, not something like John Doe.
  4. 写一个假名字,用一个听起来真实的名字,而不是像约翰 · 多伊那样的名字。
  5. When choosing your email address, don’t include any personal information. In addition, don’t use anything that you have used as a username somewhere else.
  6. 在选择你的电子邮件地址时,不要包含任何个人信息。此外,不要使用任何你在其他地方用作用户名的东西。
  7. If Gmail asks you for a phone number, don’t give them your real phone number! Instead, get a phone number using the Text+ app. The reason I like Text+ is that you don’t need to add an email address to sign up for a number. That way, you become even less traceable. You do need a username for Text+, so choose one you have never used before, and never use it again.
  8. 如果 Gmail 问你电话号码,不要给他们你的真实电话号码!相反,使用 Text + 应用程序获取一个电话号码。我喜欢 Text + 的原因是,你不需要添加一个电子邮件地址来注册一个号码。这样你就更难被追踪了。你确实需要一个 Text + 的用户名,所以选择一个你以前从未使用过的,并且永远不要再使用它。

A Note About Anonymous Email Account Providers

关于匿名电子邮件帐户提供商的注意事项

Some email account providers have promised to keep user information secret, but they did not keep their side of the deal. For example, Hushmail is a popular “secret” account provider.

一些电子邮件帐户提供商已经承诺对用户信息保密,但是他们并没有遵守他们的承诺。例如,Hushmail 是一个流行的“秘密”帐户提供程序。

However, when the Canadian government served them a court order with regard to steroid smugglers, Hushmail was quick to hand over CDs full of personal data and private information. Hushmail showed they can’t be trusted.

然而,当加拿大政府向他们提供有关类固醇走私的法庭命令时,侯希梅尔很快交出了装满个人数据和私人信息的光盘。哈什梅尔证明了他们是不可信的。

Instead, you want a service provider like Lavabit, which actually shut down instead of complying with government requests for user data. Consider researching an email account provider to see whether they have complied with court orders and handed over data before using them.

相反,你需要一个像 Lavabit 这样的服务提供商,它实际上是关闭的,而不是遵从政府对用户数据的要求。考虑研究一下电子邮件帐户提供商,看看他们是否遵守了法院的命令,在使用之前交出了数据。

Another interesting choice is SAFe-mail, or Safe-Mail.net. According to a Forbes article from a number of years ago, Safe-Mail.net became the preferred choice for users of the dark web after TorMail was seized by the FBI.

另一个有趣的选择是 SAFe-mail,或者 SAFe-mail. net。根据几年前《福布斯》杂志的一篇文章,在 TorMail 被 FBI 查封后,安全邮箱网络成为黑暗网络用户的首选。

If the dark web users who used to use TorMail are switching to Safe-Mail.net, you would assume it is safe and private. However, there are reports that it isn’t that safe and will disclose information if it has a legal requirement to do so.

如果过去使用 TorMail 的黑暗网络用户转向了 safe-mail. net,你就会认为它是安全和私密的。然而,有报道称,它并不那么安全,如果有法律要求,它会公开信息。

Wrapping It Up: What Is The Best Anonymous Email Account Provider?

什么是最好的匿名电子邮件帐户提供商?

ProtonMail is my #1 recommendation, as it not only allows you to create an anonymous email address, but you can keep it forever. You can also use their mobile apps to send and view emails.

ProtonMail 是我的第一推荐,因为它不仅允许你创建一个匿名电子邮件地址,而且你可以永远保留它。你也可以使用他们的移动应用程序发送和查看电子邮件。

A solid runner-up is Guerilla Mail. However, although any email address you create lasts forever until you manually tell the server to forget it, you can’t protect your inbox with a password.

第二名是游击队邮件。然而,尽管你创建的任何电子邮件地址都会永远存在,直到你手动告诉服务器忘记它,但是你不能用密码来保护你的收件箱。

Still, nobody can access it unless they know your real address, which is almost impossible to figure out.

尽管如此,除非他们知道你的真实地址,否则没有人可以访问它,这几乎是不可能的。

无需花生壳,阿里云解析实现内网穿透

家里闲置着一台老款的Mac mini Server,跑OS X越来越慢,索性装上了Cent OS 7,变成了一台家庭服务器,装上了Plex媒体服务器和Transmission下载服务,同时,也装上了Nginx、Mysql、MongoDB、Redis等,可以调试代码,甚至担当一些小型项目的服务器。

不过,只在家庭内网使用,功能太有限,于是接下来面临的一个问题就是内网穿透。使用过花生壳和花生棒,服务相当不稳定,而且种种受限,每要多加一个端口就要多花钱,安全性也有问题。

其实想想,内网穿透的最大难题无非就是家里是动态公网IP,每变换一次公网IP,需要重新解析一次域名。而阿里云等大型的云服务商,目前都已经实现了域名解析管理的API接口,而且基本都是立即就可生效 。

所以我的思路就是,系统运行一个定期执行的程序,每隔一段时间扫描一下最新的公网IP,如果发现最新的公网IP与域名解析到的IP地址不一致,就通过阿里云API自动更新解析设置即可。这样的花费不过每年一个域名的费用,最贵也就几十块钱。

具体实现步骤如下:

1. 阿里云设置

首先,要确定一个准备用于外网访问的域名,并将此域名转入到阿里云的云解析服务来解析。如图所示,添加需要管理的域名。

 
阿里云云解析服务

转入后,在解析设置中,设置一下A记录解析,解析的IP地址可以填当前的公网IP。如果不知道自己的公网IP,在CentOS系统下,可以输入使用以下命令获取当前的公网IP。

curl ifconfig.me

获取公网IP后,在阿里云云解析中设置完A记录解析。

 
设置A记录解析

在阿里云账户管理后台,点击右上角的账户头像,然后点击accesskeys,或者直接登陆https://ak-console.aliyun.com,获取阿里云的AccessKeyIDAccessKeySecret

 

2. 路由器设置

阿里云的设置完成后,需要对路由器设置端口映射,使外网对公网IP的端口访问能转发到内网服务器的相应端口。绝大部分的路由器都支持端口映射。

常见的服务端口包括,用于WEB访问的80端口、SSH远程管理的22端口、Mysql数据库的3306端口、Transmission下载服务管理的9091端口和Plex媒体服务的32400端口等等。不用花生壳的好处就是没有端口数量限制,想设置多少就可以设置多少。

当然,在设置端口映射之前,应确保服务器的内网IP已经设置为静态IP,而不是DHCP动态获取。

3. 服务器设置

服务器端安装好想要使用的各种服务后,别忘了在防火墙中开启相应的端口,在CentOS 7中,防火墙永久开启端口的命令是:

firewall-cmd --add-port=80/tcp --permanent

开启之后别忘了重新载入防火墙的设置以使其生效,命令如下:

firewall-cmd --reload

4. 自动更新域名解析程序

准备工作都做好了,接下来就是通过程序检测公网IP,并在公网IP发生变化时,及时更新阿里云的域名解析。

这个程序是用Python写的,先使用Python的包管理工具pip下载安装阿里云的Python SDK。如果没有安装pip,则先安装pip:

yum install pip

安装好pip后,安装阿里云的Python核心SDK以及云解析SDK:

pip install aliyun-python-sdk-core
pip install aliyun-python-sdk-alidns

导入项目所需要的包,如果缺少则使用pip安装:

import os
import json
from urllib2 import urlopen
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkalidns.request.v20150109 import DescribeDomainRecordsRequest
from aliyunsdkalidns.request.v20150109 import UpdateDomainRecordRequest

完整代码如下:

#!/usr/bin/env python
# coding= utf-8

import os
import json
from urllib2 import urlopen
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkalidns.request.v20150109 import DescribeDomainRecordsRequest
from aliyunsdkalidns.request.v20150109 import UpdateDomainRecordRequest

class DnsHandler:
    # 从阿里云开发者后台获取Access_Key_Id和Access_Key_Secret
    access_key_id = ""
    access_key_secret = ""

    # 填入自己的域名
    domain_name = ""
    # 填入二级域名的RR值
    rr_keyword = ""

    # 解析记录类型,一般为A记录
    record_type = "A"

    # 用于储存解析记录的文件名
    file_name = ".ip_addr"

    client = None
    record = None
    current_ip  = ''

    # 初始化,获取client实例
    def __init__(self):
        self.client = AcsClient(
            self.access_key_id,
            self.access_key_secret,
            self.region_id
        )
        self.record = self.get_record()
        self.current_ip = self.get_current_ip()

    # 如果公网IP发生变化,则自动修改阿里云解析记录
    def reset(self):
        if self.current_ip <> self.get_record_value():
            print self.update_record(self.current_ip)
            self.get_record()

    # 获取阿里云域名解析完整记录,并使用文件缓存
    def get_record(self):
        if os.path.isfile(self.file_name) :
            file_handler = open(self.file_name, 'r')
            r = file_handler.read()
            file_handler.close()
        else :
            request = DescribeDomainRecordsRequest.DescribeDomainRecordsRequest()
            request.set_PageSize(10)
            request.set_action_name("DescribeDomainRecords")
            request.set_DomainName(self.domain_name)
            request.set_RRKeyWord(self.rr_keyword)
            request.set_TypeKeyWord(self.record_type)
            r = self.client.do_action_with_exception(request)
            file_handler = open(self.file_name, 'w')
            file_handler.write(r)
            file_handler.close()
        return json.loads(r)

    # 获取阿里云域名解析记录ID
    def get_record_id(self) :
        return self.record["DomainRecords"]["Record"][0]["RecordId"]

    # 获取当前域名解析记录
    def get_record_value(self) :
        return self.record["DomainRecords"]["Record"][0]["Value"]

    # 修改阿里云解析记录
    def update_record(self, value):
        request = UpdateDomainRecordRequest.UpdateDomainRecordRequest()
        request.set_action_name("UpdateDomainRecord")
        request.set_RecordId(self.get_record_id())
        request.set_Type(self.record_type)
        request.set_RR(self.rr_keyword)
        request.set_Value(value)
        return self.client.do_action_with_exception(request)

    # 获取当前公网IP
    def get_current_ip(self):
        return json.load(urlopen('http://jsonip.com'))['ip']

# 实例化类并启动更新程序
dns = DnsHandler()
dns.reset()

将以上代码保存为dns.py文件,并赋予执行权限:

chmod +x dns.py

5. 设置定时运行

CentOS内置有强大的计划任务工具Crontab,如果系统里没有则先使用yum安装:

yum install crontabs

首先,设置执行用户的环境变量,比如,我们使用root用户来执行这一程序,则先在用户目录下建立.profile文件,或者在已有的.profile文件下加入如下一行,以使得可以使用VI来编辑cron文件:

EDITOR=vi; export EDITOR

建立mycron文件,加入如下内容:

*/10 * * * * /root/ddns/dns.py

这意味着每10分钟执行一次任务,即扫描公网IP,若与阿里云解析不一致,则修改阿里云解析。

然后,提交crontab任务:

crontab mycron

好了,大功告成,接下来,程序会每隔10分钟自动扫描公网IP,然后自动更新阿里云的解析,速度、稳定性和安全性都远胜于第三方的DDNS服务。
