I did not say that these should be combined into one aggregatable block 
at all. I said that if we were to allocate a /32 for use of DNS root 
nameservers, that we would have 8 /35s herein, and 16 /35s if we were to 
allocate a /31 for the use of DNS. All three RIRs would then have 24 or 48 
of these /35 TLAs respectively.


By the way, some paragraphs down the line I actually DID propose to
create an administrative hierarchy based on /48 aggregates but I fully
realise that his is going out on a limb. I think however, that if we
were to use 'n' TLAs for nameservers, that I would prefer to see 'n'
/48s in my routing table than 'n' /35s, this of course from the
conservation point of view.

The same holds for Internet Exchanges. Perhaps for other sites as well.
How do we plan to have AMS-IX reachable from networks that do not peer
with AS1200, if the AMS-IX is assigned only a /48 ? I see two
possibilities (obvious ones, that is).
1. Allocate /35 to AMS-IX and let it announce that from AS1200
2. Make global policy to have 2001:7f8::/32 prefixlen 48 and lower
allowable.

This latter solution could be extended to any number of services and
sites. Sorry if I am rocking the boat here ;-)

Pim
