You mean: the ip-address that someone else needs to connect

As you know how a local ip-address does look like you can remove it
from the list.

But your idea that a machine can determine it's internet-ip
does not hold in most cases. If the machine is behind a router for instance.

The only reliable way is to ask somebody else.

Just click this link.

You could parse the resulting page if you got the page from a
HTTP component.
