从IP地址获取主机名 [英] Get host name from IP address

问题描述

我设法使用下面的代码获取了连接的客户端IP，但似乎无法获取主机名。

I have managed to get the connected clients IP with the code below but can't seem to get the hostname.

Globals.connectedIPAddress = "" + IPAddress.Parse(((
    IPEndPoint)_client.Client.RemoteEndPoint).Address.ToString());

推荐答案

不是每个IP地址都有一个名称。但是，给定 IPAddress ，您可以使用 Dns.GetHostEntry 到 try 来解决它。还要注意，如果它是NAT路由器，那么您将获得路由器的IP地址，而不是其实际计算机。

Well, not every IP address has a name. However, given the IPAddress you can use Dns.GetHostEntry to try to resolve it. Also note that if it's being a NAT router, you'll be getting the router's IP address rather than their actual machine.

只是为了解决注释中的问题，我同意ToString / Parse / ToString没有意义：

And just to address the point in the comments, I agree that there's no point in ToString/Parse/ToString:

IPAddress address = ((IPEndPoint)_client.Client.RemoteEndPoint).Address;
Globals.connectedIPAddress = address.ToString();
