And they won't look for blocks that simply aren't in whois?
I don't buy the argument. The hijackers have no trouble finding the
blocks. This fallacious argument was used for a long time to block
efforts to get these blocks marked in public view. We finally came
to realize that marking them publicly allows for filtration to prevent
Obscuring the existence of the blocks does nothing to stop
hijacking. Marking them visibly does.

While I agree there is minimal value in reissuing, I think it is

Until they end up in a routing war with the prior holder or in
a protracted legal battle they didn't expect to be involved in
as a codefendant to ARIN.
I think that Mr. Hannigan's $40/IP is a rather inflated view of
the value of IPv4. At that price, IPv6 is cost effective almost
regardless of the amount of hardware you have to replace.
Many of the other more spectacular numbers have been even
more inflated (I've heard as much as $1,000 per IP). I simply
don't think they are real.
