Timeline (5)

Every change the tracker has found, newest first. It covers ARIN from 2008-12-01, the RIPE NCC from 2010-04-23, APNIC from 2008-02-15, LACNIC from 2012-06-29 and AFRINIC from 2012-10-03.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2027-05-05. 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 2023-10-24) on 2026-11-04 and reserved on 2026-11-06. 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 2027-05-05. This does not confirm availability. Since mid-2024, ARIN has released many ASNs within two months, before the 6 calendar months were up, so the release can come sooner.

No transfer record matches. ARIN's statistics show it available on 2023-10-23 and assigned (dated 2023-10-24) on 2023-10-25. The tracker saw this range released from hold on 2023-10-11 (AS396856), so it appears to have been issued again from ARIN's pool.

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

ARIN's statistics show it reserved on 2023-10-10 and available on 2023-10-12. 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 2022-10-10, 366 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

Hold estimate
Estimated hold end 2023-04-10. 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 2018-05-04) on 2022-10-09 and reserved on 2022-10-11. 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 2023-04-10. This does not confirm availability.

No transfer record matches. ARIN's statistics show it available on 2018-05-03 and assigned (dated 2018-05-04) on 2018-05-05. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.
