How can you get your external IP address from powershell? I use a simple script to query an external public web service. The service I’m using is hosted by ipinfo.io . I have created a small function that is placed in my powershell library. All my modules are loaded by using powershell profiles.

This simple function uses rest. Usage is simple : get-mypublicip . Could easily be uses in script (get-mypublicip).ip .

function get-mypublicip{

    Write-Verbose "Resolving external IP"

    try { 

        $ipaddr = Invoke-RestMethod http://ipinfo.io/json #| Select-Object -ExpandProperty ip 

        }

    catch { 

        throw "Can't get external IP Address. Quitting." 

        }

    if ($ipaddr -eq $null) { throw "Can't get external IP Address. Quitting." }

    Write-Verbose "External IP is $ipaddr"

    return $ipaddr

}
