Exactly.
If you start with an IP address and you're trying to get to some
real-world entity, then you can check routing of the block or the=20
Whois entry... this will get your to an ISP, but then you get to=20
repeat the process by contacting that ISP and repeating the query
(and potentially again if their customer is an even smaller ISP=20
or hosting firm, etc.)
With reasonable Whois update practices, Whois will get you to the=20
ultimate non-residential organization much faster (which can make=20
a difference in many situations.) The entire process can be pursued=20
via contacting ISPs serially and asking them to check their routing=20
and customer records, but that approach is definitely slower and far
most costly for both government and industry.
