or
using System.Net;
strHostName = DNS.GetHostName ();


// Then using host name, get the IP address list..
IPHostEntry ipEntry = DNS.GetHostByName (strHostName);
IPAddress [] addr = ipEntry.AddressList;

for (int i = 0; i < addr.Length; i++)
{

I use the following found at: https://stackoverflow.com/a/27376368/2510099 for the IP address

public string GetIPAddress()
{    
   string ipAddress = null;

   using (Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, 0))
   {
      socket.Connect("8.8.8.8", 65530); //Google public DNS and port
      IPEndPoint endPoint = socket.LocalEndPoint as IPEndPoint;
      ipAddress = endPoint.Address.ToString();
   }

   return ipAddress;
}

and for the machine name

Environment.MachineName;
