Secondly, at the time, a 9600 baud leased line was a *high speed* link,
and 56KB was "long haul backbone link". The added 4 bytes/packet would
be noticable at that speed.
In my opinion, adding any useless bits or bytes in the IP headers is not a
good thing.
With IPv16, we move the 4 bit version number out, as an implied constant. If
one
is connected, they assume that version. It makes no sense to waste 4 bits in
each
packet for a constant version number.
In the same 20 byte foot-print, various trade-offs yield more space for
address bits.
IPv4 is clearly very wasteful.
IPv4 - 40%
IPv8 - 59%
IPv16 - 80%
