Resolving numerical adresses

[Vidar Ringstr|m]

Hello all

I'm doing an analysis of a weblog, and wonder if anyone can enlighten me 
on a minor problem.

As you all probably know a weblog includes IP-numbers and "ordinary"
adresses of the machine.subdomain.domain-type. Through whois-services and
programs like traceroute I have been able to find out who is behind the 
IP-numbers that have logged most visits.

But can anyone tell me where the log pics up the machinename/IP-number? 
Is it from the browser? 

The statistics program (Analog) lists IP-numbers 
under the heading ]Unresolved numerical adresses], does this mean that 
they have failed a resolving process?

Regards,
