Current Status of Phase 4 of the IPv4 Countdown Plan

Current Status of Phase 4 of the IPv4 Countdown Plan

 • Leslie Nobile

ARIN has implemented Phase 4 of our IPv4 Countdown Plan, and as a result, our response time for IPv4 requests has increased from our organizational goal of two business days. We acknowledge that this situation has caused some frustration in the community, and we are making adjustments to our IPv4 request procedures in an effort to improve response time. But the first question is what changed in Phase 4, and why? First - Phase 4 requires “team review” for all IPv4 requests. This allows us to ensure all organizations are being reviewed under the same set of requirements. By having at least two analysts review each new IPv4 request (and responses to an existing IPv4 requests), we have additional verification that each is handled in accordance with policy.
