No transfer record matches. ARIN's statistics show it reserved on 2024-09-23 and assigned (dated 2024-09-24) on 2024-09-25. The tracker saw this range released from hold on 2024-09-23 (AS15204), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2024-09-23: Remove AS15204), so the before-and-after statistics may include it.

Inventory effect unknown

ARIN's statistics show it reserved on 2024-09-22 and assigned (dated 2024-09-24) on 2024-09-24. 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 (2024-09-24: Add AS15204), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2024-07-08. 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 2018-04-16) on 2024-01-07 and reserved on 2024-01-09. 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 2024-07-08. This does not confirm availability.

No transfer record matches. ARIN's statistics show it available on 2018-04-15 and assigned (dated 2018-04-16) on 2018-04-17. The tracker saw this range released from hold on 2018-04-13 (AS15204), so it appears to have been issued again from ARIN's pool.

Remove AS15204
Inventory
ARIN's statistics now list it as 'available'; reissue not confirmed

ARIN's statistics show it reserved on 2018-04-12 and available on 2018-04-14. ARIN took it out of its reserved (held) records; its statistics now give it the status 'available'. The tracker saw it removed from registration on 2017-10-16, 179 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics.

Hold estimate
Estimated hold end 2013-01-30. 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 2008-12-10) on 2012-07-29 and not issued on 2012-07-31. (Until 2013-03-05, ARIN's statistics list only what's issued.) 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 2013-01-30. This does not confirm availability.

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.
