Geoff,
Your proposal is reasonable at this time. However, if you permit a
previously allocation block to break into many separate /24s when transfer,
then how about the aggregation goal. I'm wonder why this proposal do not
base on current IPv4 management policy, that mean, the condition to transfer
is /21 size address block with previously allocation block and /24 size
address block with previously multihoming assignment.
Looking at the BGP table today, I'm left wondering if aggregation is a
goal for anyone any more. It's fine for the RIRs to say aggregation is
important, and I can give presentations saying it is important, but then
I look at the BGP table and see that of the 227k prefixes, there are
almost 120k of those that are /24s. So many of the RIR minimum
allocations have been chopped into /24s, and the vast majority of them
seem to have no good reason for doing so.
(I'm not justifying the desire to split previously allocated blocks in
the transfer proposal, just observing that it's not creating an
additional problem.)
