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

I don’t support this policy.

I’ll echo what other operators have said, renumbering is non-trivial at an IXP.

Is ARIN even able to provide reverse DNS delegation for a /26 at this point?

The CI pool is in my mind working as intended, the drawn down from the pool as shown earlier has been reasonable.

If the definition of who is an IXP for the purposes of getting space, that is an entirely different proposal and problem statement. In 4.4 it does say “ARIN will make a list of these blocks publicly available.” Is that information available with the IXP name etc?

It's clear this proposal did not receive feedback from those of us who operate IXP's (or those who lived through the ep.net<http://ep.net> era). Renumbering events are often multi-year efforts for an IXP, this "savings" is not worth the operational overhead. I'm not in support of this proposal. This is a solution looking for a problem, we have both the appropriate pool size and a method to refill.

If anything, the 4.4 requirement language around "other participants (minimum of three total)" could use some attention. ARIN's service region has many "shadow IXP's", which may have 3 unique ASN's (say a route server, route collector, and management network) - but are all operated by the same organization. That does not seem like a legitimate definition of an exchange point, especially when that operator is the only participant over several years.
