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 
Whois entry... this will get your to an ISP, but then you get to 
repeat the process by contacting that ISP and repeating the query
(and potentially again if their customer is an even smaller ISP 
or hosting firm, etc.)

With reasonable Whois update practices, Whois will get you to the 
ultimate non-residential organization much faster (which can make 
a difference in many situations.) The entire process can be pursued 
via contacting ISPs serially and asking them to check their routing 
and customer records, but that approach is definitely slower and far
most costly for both government and industry.
