If you want to go on a wild goose chase, start chasing down 240/4 and
you might make some progress.

As i have mentioned before, it was only after i gave up on 240/4 for
private network numbering that i really earnestly took on IPv6-only as
a strategy.  Seeing 240/4 actually work would be nice, but i have
already concluded it does not fit my exhaustion timeline given how
many edge devices will never support it.

If i have to fork lift, it should be for ipv6.
