That is, IPv6 really hurts.
I'm in the alarm industry and they still haven't started adopting
IPv6. If we allow /25 subnets, some industries will never change. In
a sense, we have to “force” them to change.
FYI, WRT routing table bloat, IPv6 having a lot longer minimum
allocation prefix than /24 (which forbid operators cut IPv6
prefixes longer than /24), that is, a lot beyond direct SRAM
look up, and, worse, needing longer TCAM word size (64 or 128
bits?) than IPv4, is, in a not so long run, a lot lot worse
than IPv4.
