Yes, and I'll second this -- PageRank does not in any way get improved  
by hosting on multiple IPs (or different ranges or Class A's or Class- 
C's[0] or swamp space or space from different RIRs or "premium  
addresses" (?!) or anything like that...).

There's Matt's word and Craig Silverstein's word and (not that it  
count for as much) my word -- PageRank does NOT differentiate between / 
24's.

Google has stated this multiple times and we have nothing to gain by  
lying or making things up -- the SEO folks on the other hand have a  
large incentive to claim that IPs *do* make a difference as they sell  
this as a service...
