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.

2025-08-11 ARIN Not in ARIN-Issued Removed (return, revocation or reclamation not publicly distinguishable) Strong inference

Inventory: Possible future reissue candidate after hold
Hold estimate: Estimated hold end 2026-02-11. 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 2021-03-31) on 2025-08-10 and reserved on 2025-08-12. 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 2026-02-11. 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.

2021-03-31 ARIN + Add Apparent reissuance of previously removed resource Strong inference

ARIN-Issued: Add AS29927
Inventory: Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it available on 2021-03-30 and assigned (dated 2021-03-31) on 2021-04-01. The tracker saw this range released from hold on 2020-09-16 (AS29927), so it appears to have been issued again from ARIN's pool.

2020-09-16 ARIN − Remove Released from hold (ARIN lists it as 'available') Strong inference

ARIN-Issued: Remove AS29927
Inventory: ARIN's statistics now list it as 'available'; reissue not confirmed

ARIN's statistics show it reserved on 2020-09-15 and available on 2020-09-17. 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 2015-08-11, 1863 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

Transfer records

No transfer log has a transfer of any part of this ASN.

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.
