ARIN would like to share two items of information that may be of interest to the community.
First, ARIN has recently begun to issue address space from its last contiguous /8, 104.0.0.0 /8. The minimum allocation size for this /8 will be a /24. You may wish to adjust any filters you have in place accordingly.
I was surprised that ARIN started issuing from this /8. I thought it still had a /9 and a /10 in inventory.
Additionally, ARIN has placed 23.128.0.0/10 in its reserves in accordance with the policy "Dedicated IPv4 block to facilitate IPv6 Deployment" (NRPM 4.10). There have been no allocations made from this block as of yet, however, once we do begin issuing from this block, the minimum allocation size for this /10 will be a /28 and the maximum allocation size will be a /24. You may wish to adjust any filters you have in place accordingly.
I see the note at https://www.arin.net/resources/request/ipv4_countdown.html that this block is not included in inventory. Thanks for that. Lee
