Our collective insistence on this rigid categorization and demarcation
is a bit ridiculous and produces ridiculous results more often than
should be tolerated.
Policy needs to take design into account, but design needs to do the
same. Suppose policy was that utilization could only be justified at one
/64 per household. You dont think design might come around and fix
things up or adapt to policy and operator practices instead of rigidly
the other way? Isnt that what happened with CIDR and with NAT? There has
to be proper give and take, instead of this sort of deadlock.
I consider 240/4 to be another example of this tragic comedy.
I would like to see more official liason work between protocol and
application designers, operators and policy bodies. The issue is broader
than just this forum.
From an informal outsider approach, the root of the 64 bit requirement
seems to be in
For all unicast addresses, except those that start with the binary
value 000, Interface IDs are required to be 64 bits long and to be
constructed in Modified EUI-64 format.
And this is already no longer true in almost any implementation.
This is way OT, so I would welcome further replies on this tangent off-list.
