反向 IP 域检查? [英] Reverse IP Domain Check?

问题描述

有一个网站，您可以使用域名进行查询，它会返回托管在该 IP 上的所有网站的列表.我记得在 C# 中有一种方法，类似于 ReturnAddresses 或类似的东西.有谁知道这是如何完成的?查询主机名或 IP 并返回主机名列表，即同一服务器上托管的其他网站?

There is a website which you can query with a domain and it will return a list of all the websites hosted on that IP. I remember there being a method in C# that was something like ReturnAddresses or something of that sort. Does anyone have any idea how this is done? Quering a hostname or IP and having returned a list of hostnames aka other websites hosted on the same server?

推荐答案

看完评论后，bobince 绝对是对的，这两个应该一起使用.为获得最佳结果，您应该在此处使用反向 DNS 查找以及使用被动 DNS 复制.

After reading the comments, bobince is definitely right and these 2 should be used in tandem with each other. For best results you should use the reverse DNS lookup here as well as to use the passive DNS replication.

string IpAddressString = "208.5.42.49"; //eggheadcafe

try 
{
   IPAddress hostIPAddress = IPAddress.Parse(IpAddressString);
   IPHostEntry hostInfo = Dns.GetHostByAddress(hostIPAddress);
   // Get the IP address list that resolves to the host names contained in 
   // the Alias property.
   IPAddress[] address = hostInfo.AddressList;
   // Get the alias names of the addresses in the IP address list.
   String[] alias = hostInfo.Aliases;

   Console.WriteLine("Host name : " + hostInfo.HostName);
   Console.WriteLine("
Aliases :");
   for(int index=0; index < alias.Length; index++) {
     Console.WriteLine(alias[index]);
   } 
   Console.WriteLine("
IP address list : ");
   for(int index=0; index < address.Length; index++) {
      Console.WriteLine(address[index]);
   }
}
catch(SocketException e) 
{
     Console.WriteLine("SocketException caught!!!");
   Console.WriteLine("Source : " + e.Source);
   Console.WriteLine("Message : " + e.Message);
}
catch(FormatException e)
{
     Console.WriteLine("FormatException caught!!!");
   Console.WriteLine("Source : " + e.Source);
   Console.WriteLine("Message : " + e.Message);
}
catch(ArgumentNullException e)
{
     Console.WriteLine("ArgumentNullException caught!!!");
   Console.WriteLine("Source : " + e.Source);
   Console.WriteLine("Message : " + e.Message);
}
catch(Exception e)
{
    Console.WriteLine("Exception caught!!!");
    Console.WriteLine("Source : " + e.Source);
    Console.WriteLine("Message : " + e.Message);
}
