If some registry were to give me a /8, I would carve that up
right now into ten chunks (one per SprintLink POP as of a
couple weeks from now) and subdivide those to take into
account possible growth into new cities before the current
allocations to end users were exhausted, and allow for
unexpectedly heavy or unexpectedly light allocations to
customers from those prefixes.

However, those ten chunks would be the only individual
prefixes announced out of AS1239 to the rest of the world,
in the entire /8.

Some parts of the world would even see the /8 and not the
ten individual per-POP prefixes.

This is what is done now with smaller chunks of address
space:

I expect that if Sprintlink were to propose a rational plan to
renumber and -return- the older delegations that they would be
provided with a large, single block that Sean could pursuade
Sprintlink to carve up in the fashion that he indicated.

It would go a long way in reducing the size of the global routing
system.

Methinks that this is backwards. Sprintlink clearly has a rational
plan. Obviously they cannot possibly return an older delegation until
they can get more address space.

I count 45 prefixes.

IMHO, someone needs to be following RIPE's guidelines and should be
assigning shorter prefixes to Sprint on a per-block basis.
