why do you want to stop him? seems like a crawler from a search engine and if it only requests robots.txt, this is fine, it complies to the standards.

give it a "robots.txt" with:

User-agent: *
Disallow: /

and it won´t bother you...

there is 10000s like this on the web, so you need to block quite many IPs. (i know of altavista having at least 100 different ones that showed up in my server logs already)

>> why do you want to stop him?

Good question. Same question that we have asked pentium5 dozen (100+) times without a valid reason in doing so.

Maybe he should setup some kind of access restriction in his docroot and have a default-to-deny policy.
