My computers are sitting behind a router/firewall. How do I programmatically find out what my external IP address is. I can use http://www.whatsmyip.org/ for ad-hoc queries, but the TOS don't allow for automated checks.
我的电脑正坐在路由器/防火墙后面。如何以编程方式找出我的外部IP地址。我可以使用http://www.whatsmyip.org/进行临时查询,但TOS不允许自动检查。
Any ideas?

http://ipecho.net/plain appears to be a workable alternative, as whatismyip.com now requires membership for their automated link. They very kindly appear to be offering this service for free, so please don't abuse it.
http://ipecho.net/plain似乎是一个可行的替代方案,因为whatismyip.com现在需要其自动链接的成员资格。他们非常友好地似乎是免费提供这项服务,所以请不要滥用它。

Unfortunately there is no easy way to do it.
不幸的是,没有简单的方法可以做到这一点。
I would use a site like www.whatsmyip.org and parse the output.
我会使用像www.whatsmyip.org这样的网站并解析输出。
checkip.dyndns.com returns a very simple HTML file which looks like this:
checkip.dyndns.com返回一个非常简单的HTML文件,如下所示:
<html> <head> <title>Current IP Check</title> </head> <body> Current IP Address: 84.151.156.163 </body> </html>
This should be very easy to parse. Moreover the site is exists for about ten years. There is hope that it will be around for a while.
这应该很容易解析。此外,该网站存在了大约十年。希望它会存在一段时间。

If you have access to a webserver with modphp, you can roll your own:
如果您可以访问带有modphp的网络服务器,您可以自己动手:
<?php print $_SERVER['REMOTE_ADDR']; ?>
If you don't want that to get abused, you'll have to keep it secret or add request limits.
如果您不希望被滥用,则必须保密或添加请求限制。
I've been using one on my server for years.
多年来我一直在我的服务器上使用一个。
Explicitly:
Create a file called whatismyip.php in your public_html folder in your website. It can be called anything and be anywhere in your webroot.
在您网站的public_html文件夹中创建一个名为whatismyip.php的文件。它可以被称为任何东西,并且可以在你的webroot中的任何地方。
Add the line above, and then query your server:
添加上面的行,然后查询您的服务器:
curl http://example.com/whatismyip.php
for example.
#4
Unfortunately as of 2013, whatismyip.com charge for the service.
不幸的是,截至2013年,whatismyip.com收取了该服务的费用。
http://www.icanhazip.com is still going strong, 3 years later. Just outputs the IP as text, absolutely nothing else.
3年后,http://www.icanhazip.com仍然强劲。只需输出IP作为文本,绝对没有别的。
http://checkip.dyndns.org still works as well.
http://checkip.dyndns.org仍然有效。
You can also use Google if you want to be sure it won't go down, but it can still block you for TOS violations.
如果你想确保它不会失效,你也可以使用谷歌,但它仍然可以阻止你违反TOS。
https://www.google.ie/search?q=whats+is+my+ip
But even when they block me, they still tell me my client IP address in the error message.
但即使他们阻止我,他们仍然会在错误消息中告诉我我的客户端IP地址。
#5
curl ifconfig.me
or
curl ifconfig.me/ip
Incase you don't have curl installed,
如果你没有安装curl,
wget ifconfig.me/ip 2>/dev/null && cat ip
Hope this helps.
希望这可以帮助。

If the router you are behind speak UPnP you could always use a UPnP library for whatever language you are developing in to query the router for its external ip.
如果您所在的路由器说UPnP,您可以随时使用UPnP库来处理您正在开发的任何语言,以查询路由器的外部IP。
#7
http://myexternalip.com provides this kind of information. To retrieve your IP you have plenty of options:
http://myexternalip.com提供此类信息。要检索您的IP,您有很多选择:
- http://myexternalip.com/ - browser + lot's of examples of how to use it
- http://myexternalip.com/raw - a pure text answer, only your ip, no other crap
- http://myexternalip.com/json - a resposnse ready for json-parsers, also supports jsonp
- HEAD http://myexternalip.com - send only a HEAD-request and get the answer
http://myexternalip.com/ - 浏览器+很多关于如何使用它的例子
http://myexternalip.com/raw-纯文本答案,只有你的ip,没有其他垃圾
http://myexternalip.com/json - 为json-parsers准备的resposnse,也支持jsonp
HEAD http://myexternalip.com - 只发送一个HEAD请求并得到答案

Since this question was asked a while back, there's now a freely available web service designed specifically to allow you to determine your IP address programmatically, called ipify.
由于这个问题有一段时间被问到,现在有一个免费提供的Web服务,专门用于让您以编程方式确定IP地址,称为ipify。
$ curl 'https://api.ipify.org?format=json'
Results in
{"ip": "1.2.3.4" /* your public IP */}

Another way is if you have access to a cloud email (yahoo, google, hotmail), send yourself an email. Then view the headers and you should see your IP address in there.
另一种方法是,如果您可以访问云电子邮件(yahoo,google,hotmail),请发送电子邮件给自己。然后查看标题,您应该在那里看到您的IP地址。
I would look up the exact area but the headers may vary from each implmentation, Look for the received-by and follow that until you get to something that looks like sent-by
我会查找确切的区域,但标题可能会因每个文件而异,查找收件人并按照说明直到找到看似已发送的内容

My WRT54G router tells me through its Local Router Access feature (the http(s) administration interface), and I imagine something similar could be done with many other devices. In this case, the entry page gives the octets of the IPv4 address in four lines containing this phrase:
我的WRT54G路由器通过其本地路由器访问功能(http(s)管理界面)告诉我,我想可以用许多其他设备做类似的事情。在这种情况下,条目页面以包含该短语的四行给出IPv4地址的八位字节:
class=num maxLength=3 size=3 value='i' name='wan_ipaddr_N' id='wan_ipaddr_N'
class = num maxLength = 3 size = 3 value ='i'name ='wan_ipaddr_N'id ='wan_ipaddr_N'
Where i is the octet value and N is the octet number. This bit of doggerel fetches and parses it for me, courtesy of cygwin:
其中i是八位位组值,N是八位位组数。 cygwin礼貌地说,这一串顺口溜为我提取并解析它:
#! /usr/bin/env perl
use strict;
use warnings 'all';
my( $account, $password ) = @ARGV;
open QUERY,
"curl --sslv3 --user '$account:$password' https://Linksys/ --silent |"
or die "Failed to connect to router";
my @ipaddr = ('x','x','x','x');
while( <QUERY> ) {
$ipaddr[$2] = $1 if /value='(\d+)' name='wan_ipaddr_([0-3])/;
}
close QUERY;
print join('.', @ipaddr);
There is no guarantee that this will work with all versions of the router firmware.
无法保证这适用于所有版本的路由器固件。
If your router is set to use http for this interface, drop the --sslv3 curl option, and you can use dotted-decimal notation to address the router. To use https with the curl options above, I also did this:
如果您的路由器设置为使用此接口的http,请删除--sslv3 curl选项,您可以使用点分十进制表示法来寻址路由器。要使用https与上面的curl选项,我也这样做:
-
Used a browser to fetch the router's self-signed certificate (saved as Linksys.crt).
使用浏览器获取路由器的自签名证书(保存为Linksys.crt)。
-
Added it to my CA bundle:
将其添加到我的CA包中:
openssl x509 -in Linksys.crt -text >> /usr/ssl/certs/ca-bundle.crt - Added 'Linksys' to my hosts file (C:\Windows\System32\Drivers\etc\HOSTS on my Win8 box), as an alias for the router's address. If the dotted-decimal notation is given to curl instead of this alias, it rejects the connection on account of a certificate subject name mismatch.
将“Linksys”添加到我的主机文件(我的Win8盒子上的C:\ Windows \ System32 \ Drivers \ etc \ HOSTS),作为路由器地址的别名。如果将点分十进制表示法赋予curl而不是此别名,则它会因证书主题名称不匹配而拒绝连接。
Alternatively, you could just use the --insecure option to bypass certificate verification, which probably makes more sense in the circumstances.
或者,您可以使用--insecure选项绕过证书验证,这可能在这种情况下更有意义。

Simple but not elegant for this use.

这种用途简单但不优雅。我安装了一些安全摄像头和我的有线电视提供商--Broad Open West或WOWWAY每月需要10美元来设置一个静态IP - EXTORTION用于DHCP预留...所以,我用以下代码创建了一个VBS文件,将结果删除dropbox和google drive ...由于某种原因,必须删除要同步的新文件。
