[arin-ppml] Draft Policy ARIN-2023-2: /26 initial IPv4 allocation for IXPs

[David Farmer]

Actually, I expect the genesis of this proposal was the very similar
proposal in the RIPE community RIPE-2023-02 Reducing IXP IPv4 assignment
default size to a /26. That proposal followed a presentation at RIPE 86
last fall and a discussion on their address-policy-wg mailing late last
year. The conversation started with a reduction to /29, and a reasonable
compromise of /26 that was written in to a formal proposal earlier this
year. That proposal is progressing through their process and just finished
their Discussion Phase last week, and has entered their Review Phase, and
at least seems to be heading towards being policy in the RIPE community.

While I do not support this proposal, especially as written, it is
nevertheless an important and timely conversation for the ARIN community to
have and I for one appreciate it being brought forward to our community as
a proposal.

Thanks.
