In my recent probe of route servers, I found 22 legacy /8's that were partly
or completely unused. I'm a little surprised ARIN/ICANN thinks it's a waste
of time to even try to reclaim them.
Because it is a waste of time and money.
That's an assertion I've heard, but has anyone quantified it? How much time and money would it take? Has anyone just asked the 22 /8 holders mentioned above nicely if they might just like to give them back for some good publicity? You know, US DoD migrates to IPv6 and returns X /8s for the good of the American people (assume ARIN) so that broadband might continue to grow and thrive in the land of the free?

Multiple times. The most optimistic estimates are on the order of 4 years. The most optimistic estimates of the return rate are on the order of 6-8 /8s (not the 100% of 22 /8s you are postulating). The legal expenses would be extreme. So, for $ALOT and 4 years of effort, you might get back as much as 4 months of address space. Next? Owen
