I think the GetHostbyAddress() method can help you. the followed code is copyed from msdn: 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("\nAliases :"); for(int index=0; index < alias.Length; index++) { Console.WriteLine(alias[index]); } Console.WriteLine("\nIP 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); } Just do it!
