如何从C＃中的给定IP获取域名？ [英] How to get domain name from Given IP in C#?

问题描述

我想从给定IP获取域名。
例如，如果我将IP设置为 172.24.17.85，则应该只获得域名，例如我的域名是sonata.net。

I want to get domain name from a given IP. E.g If I give IP as "172.24.17.85" I should get only domain name like my domain name is sonata.net.

任何此代码段在C＃中？

Any code snippet for this in C#?

推荐答案

您是否尝试过 Dns.GetHostEntry ？

Have you tried Dns.GetHostEntry?

示例：

using System;
using System.Net;

class Test
{
    static void Main(string[] args)
    {
        IPAddress addr = IPAddress.Parse("69.59.196.211");
        IPHostEntry entry = Dns.GetHostEntry(addr);
        Console.WriteLine(entry.HostName); // Prints "stackoverflow.com"
    }
}

不适用于您给出的示例...如果反向DNS查找不起作用，我不确定您能做什么。

Note that this didn't work for the example you gave... if a reverse DNS lookup doesn't work, I'm not sure what you can do.
