How Can I Access My Router's Public IP Address?

Locating Your Router's Public IP Address

Determining your router's public IP address might seem tricky, but several methods make it straightforward.

Retrieving the IP via HTTP Request

Using C#, you can leverage HTTPClient to obtain your public IP:

<code class="language-csharp">public static async Task<IPAddress> GetExternalIpAddress()
{
    string externalIpString = (await new HttpClient().GetStringAsync("http://icanhazip.com"))
        .Replace("\r\n", "").Replace("\n", "").Trim();
    if (!IPAddress.TryParse(externalIpString, out IPAddress ipAddress)) return null;
    return ipAddress;
}</code>

Another option using WebClient:

<code class="language-csharp">public static void Main(string[] args)
{
    string externalIpString = new WebClient().DownloadString("http://icanhazip.com").Replace("\r\n", "").Replace("\n", "").Trim();
    IPAddress externalIp = IPAddress.Parse(externalIpString);

    Console.WriteLine(externalIp.ToString());
}</code>

Command-Line Solutions

Command-line users have several choices:

• On Linux and Windows:

  <code class="language-bash">  wget -qO- http://bot.whatismyipaddress.com</code>

• Using Curl:

  <code class="language-bash">  curl http://ipinfo.io/ip</code>
