[address-policy-wg] 2017-03 New Policy Proposal (Reducing Initial IPv4 Allocation, aiming to preserve a minimum of IPv4 space)

To quote from the document:

"Q: How would folk announce longer prefixes for DDoS protection?
Mitigation/counter-argument: As operators accept /24s today, when the
allocation size is a /22, it might be wise to accept prefixes longer
than a /24 when the allocation size is /24. Of course, this would be
in the well-documented address range(s) where /24s are allocated."

-- okay, this is fine... wait...

"Summary of Proposal

[..]If the minimum globally-routable prefix changes from a /24 to a
smaller prefix, the initial IPv4 allocation should also change to
match."

-- so, how do those things match?

The issue about announcing longer prefixes is one hundred percent
correct. As of now, reducing the initial allocation to /24 renders
newcomers unable to make use of trivial BGP failover mechanisms. I'd
support the idea, but no earlier than the minimum globally-routable
IPv4 prefix is changed to /25. Or, to say, initial allocation might be
/25 if the MGRP will be /26.
