analogous to one's need for ipv4 reachability until the last ipv4 sites
die out, if any equipment does not properly route and forward 240/4 then
there will be folk who can not reach those with addresses drawn from
that space.

darned shame but we do need universal reachability.

we do not have a good track record for addressing architectures.  check
out rfc 2450 when you have not eaten recently.
