All, Apologies if this is a resend; I replied to one of these threads in August of 2025, though my most doesn't seem to have made it into the archive.
1. I'm unsure if the change is necessary; it feels unnecessarily protective. Has there been an influx in requests to use 4.10 space out of the region? Especially given ARIN's current practice of requiring entities to be in-region, this feels like it would primarily impact a small-subset of users. This is especially true given NPRM section 9, which would necessitate an entire /22 of space being used in-region. If an entity were only using 4.10 space, they'd need to put in a pretty substantial amount of time and effort for relatively little reward. Some scripting on the ftp file suggests roughly 17.8% of 4.10 space has been allocated (with only 26 entities having more than a /22 or more of 4.10 space); while that's not nothing, the burn rate doesn't seem particularly concerning to me. A few allocations for out of region use (to in-region entities) doesn't feel problematic. 2. Echoing Owen's concerns, the wording seems ambiguous. The staff interpretation seems to have deviated into the intent and not the actual wording - facilitating deployment within the service area is not necessarily the same as being used within the service area. Given how ambiguous 4.10 already is (and how it necessitates judgement calls from ARIN staff), I'm concerned at the possibility of introducing yet more ambiguity. Absent data showing a need, opposed in principle. Regardless, opposed as written.
