Before embarking in such a task, you might want to consider what
"the external IP address of your machine" actually means, just to
understand where the limitations and pitfalls of such a concept are.

Judging from that, I guess you mean "your machine as seen from the
Internet". Well, that will (in most cases) the IP address your provider
assigns to your DSL modem (or your cable modem, or whatever device
you're using to connect to the Internet). Behind that, there's (again:
most probably, but not necessarily) an NAT ("network address translation",
so your machine's IP address looks different.

For that you'll always need the cooperation of some site located in what
you consider to be "out there".
