Transferred into RIPE NCC administration; not a new issuance

The RIPE NCC's transfer log records a transfer from an unnamed organization (ARIN) to IPv4 Superhub Limited (RIPE NCC) on 2025-11-10 19:00 UTC: it came to the RIPE NCC from ARIN. It was already issued by another registry, so this is not a new issuance.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2022-01-22. Possible reissue candidate after this date; not confirmed available.

Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics. ARIN's statistics show it allocated (dated 2015-06-25) on 2021-11-22 and reserved on 2021-11-24. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv4 space for 60 days before reissuing it, so the estimated hold end is 2022-01-22. This does not confirm availability.

No transfer record matches. ARIN's statistics show it available on 2015-06-24 and allocated (dated 2015-06-25) on 2015-06-26. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

ARIN's statistics show it available on 2015-06-24 and allocated (dated 2015-06-25) on 2015-06-26. ARIN removed its own pool record for this range as part of issuing it: the same report adds 172.110.208.0-172.110.223.255. The issuance is explained on that line.

RDAP lookups

Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
