Since you mentioned Hilco specifically. . . IPv4.Global is the IPv4 address brokerage operated by Hilco Streambank. We match organizations who have more IPv4 address space than they need with organizations who need more IPv4 address space than they have. This is consistent with ARIN's Number Resource Policy Manual sections 8.3. and 8.4 https://www.arin.net/participate/policy/nrpm/#8-3-transfers-between-specifie... I was on the ARIN Board when we approved this policy in 2008. The compelling argument to me was that this market would improve overall utilization of address space, and would be more efficient than ARIN trying to reclaim unused or lightly used address blocks. There are a lot of cases where pre-RIR, the justification was minimal, and organizational needs may change over the intervening 20-40 years. Part of the interest, to me, was that many organizations who had received their allocations prior to ARIN's existence did not recognize ARIN's authority to reclaim their space. Even if ARIN prevailed in court, it would have been costly. Not only that, but there's no minimum utilization requirement to keep addresses. You must show 50-80% utilization to get more, but what if you aren't asking for more? Would ARIN reclaim a block that was only 45% used? 25%? 1%? In each of the more than 1500 transfers IPv4.Global has handled, the recipient has had to satisfy their need under the rules of the RIR in which they operate. ARIN's policies are established by community consensus. ARIN's Public Policy Mailing List (ppml) is open, and there's a designated open microphone time at the end of the meeting next Thursday. If you won't be there in person, remote participation is pretty good. I'm always happy to talk about this, either one on one, or if there are other folks at NANOG/ARIN next week who want to get together to chat, I'd be happy to facilitate.

A thought crossed my mind the other day as I was having a discussion with someone.
Every entity is suppose to justify their need for IPv4 address space from ARIN. This was always (in recent history) the case.
No entity is suppose to be given more IPv4 space until they have nearly exhausted their previous space.
How is it, then, that we daily for the last 2-3 years have places like Hilco that have sometimes 15-20 large IPv4 blocks up for auction?
Supposedly we are completely out of IPv4 space, yet every day large blocks are being sold for money, yet they were never returned because they weren’t needed.
Another thought: being that IPv4 address space is essentially leased to you from ARIN, can you even legally auction your space to someone else? I know it’s happening, but it would almost be like me auctioning my apartment to another random person.
