On Tuesday, 13 January 2026, ARIN fulfilled 149 requests off the IPv4 Waiting List from the 59 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about the reputation of these address blocks, causing these blocks to be placed on a blocklist, are most likely no longer valid.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 first quarter of 2026. We will notify the community and update the list of blocks used to fulfill Waiting List requests at that time.
