Hi seo4real and welcome to WebmasterWorld :)
I'm not familiar with the term UG cloaking. Are you referring to User Agent cloaking?

IP cloaking is preferred to User Agent cloaking because it is far more secure. It's extremely easy to crack User Agent cloaking, because it is a simple matter to fake your User Agent and visit a cloaked page masquerading as Googlebot.
Changing 500 sites to IP cloaking would be a tall order, though.

But how u get an updated list of all the IP's?

Decent IP cloaking software will update your IP list automatically when new robots are detected.
There are IP lists out there is you look. Try google for "IP lists" and you should find what you are looking for.

There are other environmental variables that can be used for cloaking purposes other than REMOTE_ADDR or HTTP_USER_AGENT such as: HTTP_REFERER, REMOTE_HOST, HTTP_ACCEPT_LANGUAGE, HTTP_COOKIE, and many others. Pay attention to what connections from spiders "look like" in whole not just what their IP is.

While upside is correct, if you are at all serious about cloaking, you should cloak by identifying the IP address of the visitor as belonging to a search engine. Every other indicator (save possibly REMOTE_HOST) can be spoofed.
