Policy Block 1: Recommended Draft Policy ARIN-2025-8#
ARIN 58 Public Policy and Members Meeting digest Program Adjacent pick 22–23 October 2026
Kaitlyn Pellak (Advisory Council; co-drafted with E. Marie Brierley)
- Why: Closes an abuse vector in the last ARIN-controlled IPv4 pool — relevant to anyone tracking where fraudulent IPv4 leasing/announcement pressure comes from.
- What: Codifies that 4.10 space (dedicated IPv4 allocations to facilitate IPv6 deployment) may only be used within the ARIN service region, adding "within the ARIN service area" to NRPM 4.10. ARIN's Registry Integrity Report identified 4.10 as the highest-target pool for fraud: announced out of region, reassigned to customers, leased, or announced with no associated IPv6.
- How: One-sentence amendment codifying existing staff practice; implementable in 3 months, overwhelmingly positive meeting feedback.
- Where applicable: 4.10-space holders only, but a useful data point on which IPv4 pools fraudsters target as scarcity deepens.
