How to get the User IP Address?

It's very easy to get IP address,we have to import System.Net namespace to get IP addresses.

private string local_IP_Address()
{
        string local_IP_address = string.Empty;

        try
        {
            System.Net.IPHostEntry host;
            
            host = System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName());
            foreach (System.Net.IPAddress ip in host.AddressList)
            {
                if (ip.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
                {
                    local_IP_address = ip.ToString();
                    break;
                }
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
        return local_IP_address;
}
