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

Fast way to get External ip without any connection Actualy no need any Http connection for that

first you must add NATUPNPLib.dll on Referance And select it from referances and check from properties window Embed Interop Type to False

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using NATUPNPLib; // Add this dll from referance and chande Embed Interop Interop to false from properties panel on visual studio
using System.Net;

namespace Client
{
    class NATTRAVERSAL
    {
        //This is code for get external ip
        private void NAT_TRAVERSAL_ACT()
        {
            UPnPNATClass uPnP = new UPnPNATClass();
            IStaticPortMappingCollection map = uPnP.StaticPortMappingCollection;

            foreach (IStaticPortMapping item in map)
            {
                    Debug.Print(item.ExternalIPAddress); //This line will give you external ip as string
                    break;
            }
        }
    }
}
