When I use the ifconfig.me service, by running the following command:

$> curl ifconfig.me/forwarded

I returns a list of IP addresses. does anyone know what this IP addresses are. I am behind a proxy, so I assume it has something to do with that.

It looks like the service looks at the X-Forwarded-For field in the http request. This is (optionally) added by proxy servers in the path, referencing the IP address of the device they are requesting on behalf of.
