Update: ARIN IPv4 Waitlist

July 6, 2023

The following is an update to our June 14 alert.

ARIN issued about 45,000 addresses to 63 organizations on 5 July 2023. 617 organizations remain on the list, waiting for addresses. This is an increase of 56 since April 2023.

ARIN reports that almost 700,000 addresses have been transferred between ARIN region organizations so far this year. Just over 1 million addresses have been transferred in and out of the region in the same period.

The organization that has been waiting the longest, joined the queue in June 2022. They will have to wait at least until the next distribution in October 2023.

On average, they want 669 addresses but would accept 648. This is almost the same as last quarter. It means their average need is a /23 and a /24. This is because IPv4 addresses are issued in CIDR blocks. The smallest block size available is a /24, which is 256 addresses.

ARIN warned that the wait time for IPv4 space from its Waitlist is years, not months, at NANOG 88 in Seattle.

There were 632 requests on the list at the end of May 2023 and it grew by 429 requests in the last year.

Why is there such a long wait from ARIN?

The long wait comes despite ARIN fulfilling 136 requests in Q1 2023. This compares with 151 in the previous three quarters. John Sweeting, ARIN’s Chief Customer Officer explained that this is the result of an influx of reclaimed IPv4 space that is unlikely to be repeated.

ARIN completed 373 transfers by the end of May 2023. This is about 75 per month, while 2022 saw about 80 per month.

ARIN introduced a Qualified Facilitators program at the start of June. Its goal is to “get a transfer completed” so this number could grow by the end of the year.
