Navigating New ARIN Pre-Approval Rules

Published on July 25th, 2017

Slowly but surely, ARIN is chipping away at the impediment of having to justify IPv4 purchases via transfer.

Recently implemented policy changes have achieved the following:

  • In July 2016, a change was made to remove the criteria from the end-user IPv4 policy, where network operators must utilize 25% of the address space within 30 days of receiving a block. (ARIN-2015-3)
  • In February 2017, a change was made which requires buyers to show at least 50% usage of a requested block within 24 months, as opposed to 80% usage. In addition, to receive additional space companies must show usage of only 50% of their cumulative existing IPv4 address blocks. (ARIN-2016-5)

A new proposal, which is pending review, will improve things even more:

  • A change was recommended to the Board in May 2017, that will allow organizations using 80% of their current space to double their holdings via IPv4 transfers up to a /16 equivalent. (ARIN-2016-3)

These changes are good for small to medium sized ARIN members, as they specifically make it easier to request small blocks of /16 and smaller.

By the time IPv4 transfers slow to a trickle, due to decreased supply, ARIN may completely remove IPv4 transfer justification. What will come first: IPv4 transfer runout or removal of needs justification?

The good news is we are on the right path.
