AC Assessment of Conformance with the Principles of Internet Number Resource Policy:

Based on community feedback and AC discussion Draft ARIN-2023-1: Retire Slow Start has been moved to Recommended Draft. This policy, if adopted, will retire section Slow Start which served its purpose to constrain the rate of IPv4 allocations made by ARIN and has not been in use since 2018 due to the exhaustion of the IPv4 free pool and introduction of transfer policies. This Draft Policy is fair, impartial, and technically sound.

Problem Statement:

Section Slow Start has been a part of the NRPM for two decades, and successfully served to constrain the rate at which ARIN issued IPv4 address allocations to its members for many years. Following the exhaustion of the free pool, as well as the introduction and refinement of transfer policies, Slow Start has ceased to be applicable to the operations of ARIN’s registration services. Staff has confirmed that this policy has not been used since 2018.
