No transfer record matches. ARIN's statistics show it available on 2023-02-21 and assigned (dated 2023-02-22) on 2023-02-23. The tracker saw this range released from hold on 2023-02-21 (AS17387), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2023-02-21: Remove AS17387), so the before-and-after statistics may include it.

Inventory effect unknown

ARIN's statistics show it reserved on 2023-02-20 and assigned (dated 2023-02-22) on 2023-02-22. ARIN removed its own pool record for this range and the range is now registered, but the same report doesn't list it as added. Another change to this range was reported the day before or after (2023-02-22: Add AS17387), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2021-05-09. 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 assigned (dated 2018-06-14) on 2020-11-08 and reserved on 2020-11-10. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed ASNs for 6 calendar months before reissuing them, so the estimated hold end is 2021-05-09. This does not confirm availability.

No transfer record matches. ARIN's statistics show it reserved on 2018-06-13 and assigned (dated 2018-06-14) on 2018-06-15. The tracker saw this range removed from registration on 2018-03-13 (AS17387), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2018-06-13 and assigned (dated 2018-06-14) on 2018-06-15. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS17387. 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.
