First I look up the originating IP address in the source code of the SPAM message, plug it into a WhoIs look up via the IANA ipv4-address-space.xml files.
Why would you do this instead of using the whois service at whois.iana.org or http://www.iana.org/whois? The whois service will always return the most specific answer in an IANA registry. Regards, Leo
