Re: IPv6 allocations, deaggregation, etc.

The assumption that networks will filter /48s is not the whole story.
The RIRs giving out /48s do so from a single pool that only contains /
48 assignments.
The RIRs give out /32s from a pool containing /32 or shorter prefixes
(ie /31, /30, etc. etc).
You will find that most networks filtering /48s allow them from the
pool with only /48s in it.
The root DNS servers are in /48s.
If you can justify getting a /32, then I suggest you do so, but if not
then don't worry, a /48 will work just fine. The networks that do
filter you will pretty soon adapt I expect.
Insert routing table explosion religious war here, with snipes from
people saying that we need a new routing system, etc. etc.
So with that in mind, do your concerns from your original post still
make sense?
