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

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.

Mark.
