[c-nsp] IPv6

[Peter Rathlev]

As Jens points out: This has been discussed extensively in several
places before, and the NANOG list have left no stone unturned. :-)

I found this thread rather interesting, albeit long:

They realised pretty fast that the initial design didn't match the
growing popularity. That's what happens. The problem is that it has
taken us close to 30 years (!) since we discovered the issue to handle
to the situation. And we're not even there yet.

Though I would side with you on the "let's be conservative" approach,
the argument you present here isn't really relevant, neither to IPv4 nor
to IPv6.

If we were to assign /64 subnets to "end-stations" like milk cartons,
the whole point of "subnets" vanishes. No hierarchical scheme (suitable
for routing) fits that purpose as far as I can think. RFID would
probably fit better.

All in all I would personally prefer that we do _something_ and start
seriously deploying/using IPv6, and then in parallel continue discussing
address allocation policy et cetera. :-D
