    using System.Net.Sockets;

    namespace ConsoleApp3
    {
        class Program
        {
            static void Main(string[] args)
            {
                IPAddress[]ips= Dns.GetHostAddresses("Server Name");
                for (int i = 0; i < ips.Length; i++)

Take a look at NetworkInterface.GetAllNetworkInterfaces . You can browse all of the adapters, find the one you want, and retrieve the network information you need there.
