Well, I think (and I could be wrong) that they are 2 different types of programs. The IP Hide, is supposed to hide your IP address when you're online sending info out. Peer Guardian 2 prevent IP addresses from blacklists (You can choose which ones to use) from connecting to your computer - or from you connecting to those IP addresses.

I would recommend using both.

I wouldn't use -ANY- type of p2p network without Peer Guardian installed.

I hope this helps a little.
