Want ip or bot string for all popular bots.

[SBh]

All search bots has some specific part in their bot-name or bot ip by which it can be uniquely identified. Identification are done in two ways:
* By the bot string- There are certain fixed string by which it can identified as a specific bot. Like google bot it's bot name always has a part 'googlebot'. By this we can identify it as google bot.
* By it's IP address- Some bots have fixed IP address by which they crawl.

So, what I want is a list for all popular bots along with bot string or bot IP address, by which it can be uniquely identified.
Actually, I want this to make my site behave differently for search engine bots while for normal visitors it will behave normally.

I have seen this type of system in phpBB, so I was thinking to implement this in my site, for that i need the complete lists of bots.

If someone can help me please do so, it will be highly appreciated.

Not sure but probably this will help you if you're looking to track bot/crawlers; tracksite.ru/ts/web-bot-crawler-spider_tracking.html.en.html
Also you can refer some of the relevant info through the white papers mentioned in honeynet.org.

Thanks for the help that is quite helpful.
However it is not what I was looking for. I found this searchenginedictionary.com/spider-names.shtml
This one is quite matching to my need. If you find something similar to this one then let me know.

Ok.. I have a new problem
Actually I can not find any difference between the Googlebot for Search engine and Googlebot for GoogleAdSense. It seems that both use same bot with name GOOGLEBOT.
So, Can anybody tell me how to distinguish those two.
