I have read many of the Cloaking posts and just wanted to know why everyone seems to be using IP and UA cloaking for spiders? Isn't the IP alone be enough to determine who is visiting?

Basically it is good to have a fail safe method and that is why many use both. Although it does not happen very often, some SE's add new IP's to their pool of robots a few times here and there. If you just base your cloaking on IP address alone then you may get caught with your pants down. :o
