Hi Fernando,

As I understand it, ARIN's implementation of section 4.4 doesn't treat
the marketing and business sides of the IXP as qualified for a
microallocation. I haven't explicitly asked staff, but it's kinda
implicit in the routing restriction reported in the PER.

The 2024-5 draft is mute on that subject, so I expect the resulting
implementation would retain the understanding that the
business/marketing side of the IXP does not qualify for 4.4 addresses.

What's the desired outcome? Should IXPs get preference for the
business components which don't need to be part of the peering LAN?

Regards,
Bill Herrin
