If you have an IP address and you need to resolve its hostname then use the Dns.GetHostEntry method in C#.
Namespace:
using System.Net;
Program
class Program
{
static void Main(string[] args)
{
IPHostEntry iphost = Dns.GetHostEntry("127.0.0.1");
string hostName = iphost.HostName;
// Print out name.
Console.WriteLine(hostName);
Console.ReadKey();
}
}
Output of the above program…
