Not for all of their blocks...at the very least, not for ones acquired via PSI. $ whois 38.144.198.0@rwhois.cogentco.com:4321 [rwhois.cogentco.com] %rwhois V-1.5:0010b0:00 rwhois.cogentco.com %Error 230 No objects found. There are multiple systems in 38.144.198.0/24 spewing spam. How do you tell who they belong to and how much address space they have? Fortunately, in this case, reverse DNS and traceroutes make it pretty clear this is a single (entire) /24 of spammer systems.
