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?

Expanding on this answer by @suneel ranga:

static System.Net.IPAddress GetPublicIp(string serviceUrl = "https://ipinfo.io/ip")
{
    return System.Net.IPAddress.Parse(new System.Net.WebClient().DownloadString(serviceUrl));
}

Where you would use a service with System.Net.WebClient that simply shows the IP address as a string and uses the System.Net.IPAddress object. Here are a few such services*:

• https://ipinfo.io/ip/
• https://api.ipify.org/
• https://icanhazip.com/
• https://checkip.amazonaws.com/
• https://wtfismyip.com/text
