Cloaking bots list of Ip and agents

Anyone knows where to find a list of ips and agents that are
used by bots?

I read the original post (Cloaking : Webmaster World Knowledge base excerpt.) here, but the links are dead.

There are a number of resources for IP addresses and user agents of search engine spiders. You could try searching for "search engine spider ip addresses" at your favorite search engine.

thank you, i did find quite a few pages, just thought may be you could recommend your preferred site for that (without breaking the forum rules of course)

There are a lot of lists out there but some of the lists also use legacy IPs now utilized in other ways, such as mobile proxies, etc.

When you get a list, run reverse DNS on the list and make sure all of the IPs clearly identify themselves as the crawler such as "crawl-*.googlebot.com." so you don't accidentally let obsolete IPs see the wrong pages.
