IPv4 Waiting List Distribution

Posted: Monday, 13 October 2025

On Friday, 10 October 2025, ARIN fulfilled 587 requests off the IPv4 Waiting List from the 128 IPv4 blocks listed on the IPv4 Addresses Cleared for Waiting List page:

Prior inferences about the reputation of these address blocks, causing these blocks to be placed on a blocklist, are most likely no longer valid. For more information about ARIN’s IPv4 Waiting List Availability Process, please see our blog post from the ARIN Blog:

The next distribution will occur late in the fourth quarter of 2025. We will notify the community and update the list of blocks used to fulfill Waiting List requests at that time.
