In 5 years of logging I did get about 23000 different domains that 
accessed my site. For about 1000 IP address ranges I obtained the domain 
name manually via whois, mostly via Geektools. Sometimes via more 
specific whois servers, such as krnic. These 1000 domain names are a mix 
of "real" domain names, for instance from companies, universities or 
government, and service providers. It would be nice to automate this 
action, although the manual approach is workable.
