If I put up a webserver can I stop people from being able to see the sites IP?

If you dont want anyone to be able to browse the site then yes.

Understand what a DNS lookup is and how your browser finds "tekforum.co.uk" and youll understand why the answer is no.

you could use a reverse proxy, or something like an aep netilla (Which we resell:) )

A software firewall should be able to hide the site simply by not responding to packets from unknown sources. It wont entirely block any possibility of them finding it but should be good enough to stop them locating by poking it randomly.
