[afnog] IPv6 - some interesting reading

I especially find slide 10 interesting (Myth: IPv6 Space is

Some argue being "nit" about v6 space assignments is a v4 
mentality that we should shed. Perhaps. Others say the RFC's 
should be followed for BCP, especially if the RIR's give them 
a /32. Perhaps.

To each his own.

As an own position, I am old fashioned and want to *have 
control* of what addresses are running on my router's 
interfaces (EUI-64, frying my grey matter or otherwise).

In situations where I do not require the services of ND/RA, I 
cannot comprehend the need to have a /64 on a network or 
subnet (much less a Loopback or point-to-point interface) 
where the number of network elements or connections do not 
warrant that. 

Broadband assignments (assuming that single router can handle 
that many connections simultaneously), maybe; backbone 
network with 20,000 routers on the same subnet, maybe, but 
even a /96 or /112 can handle that and still have fair room, 
assuming one has that many routers or ports running stably in 
a single subnet.

But then again, to each his own.

Perhaps it's my own inability to 'shed my v4 way of thinking', as has been put forth on this and other lists, but as I look more and more at v6 I can't escape what Mark has stated above.  Waste not, want not.  deja vu and all that...
