2/ A web server is bound to an IP address. You can
find who owns this
IP by querying another set of databases. Start from the ARIN database
at
www.arin.net which might redirect you to some other databases (RIPE
for Europe, APNIC for Asiac/Pacific, LACNIC etc.).
Just remember.... getting the IP space owner does NOT get you to the person
(or even the company) responsible for the site. Since IP space is relatively
gold these days, few people own their own IPspace (minimum cost is
$2500/year). Instead, an ISP will delegate a netblock to a lower ISP, etc.
etc. So oftentimes when you find who owns the IP block in question, you are
actually several hops at least above the person responsible for the server
on that address.
Believe me... I can't count the number of times I've gotten a nastygram from
a user complaining about a server that is three companies below me.
