That happened years ago and really was a one-off. Generally nobody will recognize IPv4 blocks as assets. That leaves leasing-out addresses by incumbent address holders as the only effective financing mechanism. I'm curious if ARIN has put any thought into how encouraging leasing will affect the practice of spammers and other bad actors leasing IPv4 space, turning it into a DNSBL wasteland, lather, rinse, repeat. Jay - There’s often quite a bit of work involved in getting a prefix off most blocklists, so the burden will be fall to the lessor to explain why a given recently-polluted prefix should be removed and won’t just be let out to the same (or materially similar) party – i.e. some folks may get away with that once, but it’s very likely to work a second time. My bad - that should have read: "it’s very _unlikely_ to work a second time." Apologies, /John John Curran President and CEO American Registry for Internet Numbers
