The initial allocations will be made with a boundary of /48 to allow 
for a change to be made if the consensus in Prague is for /48 rather 
than /64.

The address allocation is for infrastructure - so it is likely to 
filtered, and it will all come from a /35 to ease filter writing.

For external facing services the address allocation comes from 
members/customers rather than this allocation.
