I would think that it's actually very easy to do when sub-allocations are SWIP'ed.

Not that I'm really defending this policy, but sub-allocations are very often not SWIPed. I'd say 75% or more of the time I'm looking a problem IP address it is part of a /19 or larger block with no sub- allocation. For example, I know for a fact that 70.167.38.132 is part of a netblock assigned to a business (I believe it is a /28 or /27). It is routed to them over a DS1 or similar cable equivalent. They run a handful of servers behind including public hosting a half dozen corporate web sites and a mail server. Clearly these addresses have been assigned to this business. Yet: owenc@corp:~$ whois 70.167.38.132Cox Communications Inc. NETBLK-COX- ATLANTA-10 (NET-70-160-0-0-1) 70.160.0.0 - 70.191.255.255 Cox Communications Inc.

Somehow I doubt if we pulled that with our /20 I doubt we'd have a /19 now.
