In conversation with some NANOG participants last week I was asked more than once for clarification or further details about 192/8, continuing from Bill's remarks Friday.

An informal survey: how many NANOG participants have asked customers to renumber out of 192/8? And for how long have you been doing this?
InterNex has been refusing to route 192/8 blocks, and has been requiring customers to renumber out of them since the presentation at the Feb. NANOG in San Diego last year. We will work with customers to replace their legacy 192/8 blocks provided they return them to the InterNIC.
IMHO the remaining major obstacle to a concerted effort at reclamation in 192/8 is the database maintenance problem. Folks with no incentive to keep their whois entries current have not been doing so-- since the typical pre-CIDR "Class C" delegate was not an ISP and has never come back for more space, the registries have limited leverage over them, with a few notable exceptions such as DDN-NIC. Accordingly, "whois" contact information simply doesn't tell you who's using a block. I haven't risked a blind survey again since the first one, but I have no reason to believe this has changed-- any takers?
I have long hoped that there would be a minimal annual fee required for the continued usage of IP blocks. Even a $50/year fee would be enough that given non-payment, blocks could more easily be reclaimed. I'd expect a longer "On-Hold" time, say 180 days, where the blocks would no longer be considered a valid announcement, but they would also not be re-allocated by the local IR. Of course, this is purely personal, and not representative of my employer. :)
I hope and expect that ARIN may be able to throw some organized effort at this problem, if the membership feels that cleaning up the database is important.
I would cast my vote in the "yes it's important" box. :)
