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.

Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it reserved on 2025-04-02 and allocated (dated 2025-04-03) on 2025-04-04. The tracker saw this range released from hold on 2024-12-26 (199.201.225.0-199.201.225.255), so it appears to have been issued again from ARIN's pool.

ARIN-Issued
Remove 199.201.225.0-199.201.225.255
Inventory
Part of the issuance reported the same day

ARIN's statistics show it reserved on 2025-04-02 and allocated (dated 2025-04-03) on 2025-04-04. ARIN removed its own pool record for this range as part of issuing it: the same report adds 199.201.225.0-199.201.225.255. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2023-12-24. 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 2015-11-03) on 2023-10-24 and reserved on 2023-10-26. 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 2023-12-24. This does not confirm availability.

ARIN-Issued
Remove 199.201.225.0-199.201.225.255
Inventory
ARIN's statistics now list it as 'available'; reissue not confirmed

ARIN's statistics show it reserved on 2014-01-21 and available on 2014-01-23. 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 2013-10-23, 91 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

No transfer record matches. ARIN's statistics show it not issued on 2012-04-30 and assigned (dated 2012-05-01) on 2012-05-02. (Until 2013-03-05, ARIN's statistics list only what's issued.) It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

No transfer log has a transfer of any part of this IPv4 range.

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.
