Get public/external IP address?

Question

I cant seem to get or find information on finding my routers public IP? Is this because it cant be done this way and would have to get it from a website?

Answer 1

I do it using HttpClient from System.Net.Http:

public static string PublicIPAddress()
{
    string uri = "http://checkip.dyndns.org/";
    string ip = String.Empty;

    using (var client = new HttpClient())
    {
        var result = client.GetAsync(uri).Result.Content.ReadAsStringAsync().Result;

        ip = result.Split(':')[1].Split('<')[0];
    }

    return ip;
}
