It doesn't have to be a public network to need globally unique =
addresses.
There is NO policy requirement to use NAT or RFC-1918 for private =
networks. Just a suggestion that folks be considerate of the community =
where they can.
I'll bet most of them would have no problem under current policy. They =
only need to show need for ~8,000,000 hosts, including subnet overhead.
If you wanted to, your medical company could have easily justified at =
least a /17 and probably a /16 under current policy.
There's really nothing to be gained from attempting to go after what =
might be reclaimed from the legacy block holders. EIther
they will return their addresses or contribute them to the market or =
they won't. Attempts at forced reclamation will only make
that situation worse and are unlikely to result in any actual =
reclamation of addresses before the conclusion of protracted
and ugly law suits that would be very expensive. Such lawsuits are =
unlikely to reach conclusion before the need for
massive quantities of IPv4 address space is in the past.
