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 had almost the same as Jesper, only I reused the webclient and disposed it correctly. Also I cleaned up some responses by removing the extra \n at the end.

    private static IPAddress GetExternalIp () {
      using (WebClient client = new WebClient()) {
        List hosts = new List();
        hosts.Add("https://icanhazip.com");
        hosts.Add("https://api.ipify.org");
        hosts.Add("https://ipinfo.io/ip");
        hosts.Add("https://wtfismyip.com/text");
        hosts.Add("https://checkip.amazonaws.com/");
        hosts.Add("https://bot.whatismyipaddress.com/");
        hosts.Add("https://ipecho.net/plain");
        foreach (String host in hosts) {
          try {
            String ipAdressString = client.DownloadString(host);
            ipAdressString = ipAdressString.Replace("\n", "");
            return IPAddress.Parse(ipAdressString);
          } catch {
          }
        }
      }
      return null;
    }
