Some ISPs force you through a proxy server. Whilst this can be made to
be completely transparent othertimes you will fine that if you access
something on port 80 you will appear to come from the Proxy server
rather than your IP address.

The work around is real simple, just use a Dyn DNS service/client that
works on a port other than port 80. That way it's pretty much
guaranteed to give your true IP address.
