With all that bitching about IPv6 how come nobody wrote an RFC for a very
simple solution to the IPv4 address exhaustion problem:
Step 1: specify an IP option for extra "low order" bits of source &
destination address. Add handling of these to the popular OSes.
Step 2: make NATs which directly connect extended addresses but also NAT
them to non-extended external IPs.
Step 3: leave backones unchanged. Gradually reduce size of allocated
blocks forcing people to NAT as above.
Step 4: watch people migrating their apps to extended addresses to avoid
dealing with NAT bogosity and resulting tech support calls & costs.
Step 5: remove NATs.
