什么是IP地址“:: 1”？ [英] What is IP address '::1'?

问题描述

我用没有网络连接本地机器上的插座播放。见下图：

  ip地址地址= IPAddress.Any; //不起作用
ip地址地址= IPAddress.Parse（:: 1）; //作品
 

那么究竟是什么 :: 1 IP地址？它是默认可用的IP地址或它的环回地址？用什么专用IP地址和网络连接的计算机上发生上述code（工作线）？

编辑：

确切code是用来绑定一个特定的IP地址到插座。在这里，它是：

 的ServicePoint SP = ServicePointManager.FindServicePoint（URI）;
sp.BindIPEndPointDelegate =新BindIPEndPoint（绑定）;
//这里的绑定委托：
私人IPEndPoint绑定（SP的ServicePoint，IPEndPoint EP，INT RetryCount重）
{
   返回新IPEndPoint（IPAddress.Parse（:: 1），0）;
}
 

解决方案

:: 1 是IPv6的环回地址。把它看成是IPv6版本 127.0.0.1 。

请参阅 http://en.wikipedia.org/wiki/Localhost

I was playing with sockets on local machine with no network connection. See below:

IPAddress address = IPAddress.Any; // doesn't work
IPAddress address = IPAddress.Parse("::1"); // works

So what is exactly ::1 IP address ? Is it the default available IP address or it's the loopback address ? what happens to above code (working line) on a machine with dedicated IP address and network connection ?

EDIT:

exact code is used to bind a specific IP address to socket. Here it is:

ServicePoint sp = ServicePointManager.FindServicePoint(uri);
sp.BindIPEndPointDelegate = new BindIPEndPoint(Bind);
// here's the bind delegate:
private IPEndPoint Bind(ServicePoint sp, IPEndPoint ep, int retryCount)
{
   return new IPEndPoint(IPAddress.Parse("::1"), 0);
}

解决方案

::1 is the loopback address in IPv6. Think of it as the IPv6 version of 127.0.0.1.
