I noticed that the ARIN Waiting List has recently decreased quite a bit. Then I found that a new company I’ve been following, along with several others, has received newly allocated IPs from this same range. The allocations might not cover the entire /16 block, but these new IP assignments don’t appear in ARIN’s cleared IPv4 blocks list <https://www.arin.net/resources/guide/ipv4/blocks_cleared/> — perhaps it just hasn’t been updated yet.
