You can find IP Address in a way given below. It works for me :) If you want only one IP then pick up first IP from the list.

var Dnshost = Dns.GetHostEntry(Dns.GetHostName());

string ipAddress = "";

IPAddress[] ipAddress = Dnshost.AddressList;
ipAddress = ipAddress[0].ToString();

Here "ipAddress[0]" will give you current IP of system. And if you want all IP's to get then iterate the AddressList as shown below:

foreach (var ip in Dnshost.AddressList)
 {
            if (ip.AddressFamily == AddressFamily.InterNetwork)
            {
                ipAddress = ip.ToString();
            }
 }

NOTE: It will give you the IPv4 Addresses in case of "AddressFamily.InterNetwork" and if you need IPv6 Addresses you will use "AddressFamily.InterNetworkV6".

Hope it will be helpful for you.
