Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2024-11-08. 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 allocated (dated 2018-05-10) on 2024-09-08 and reserved on 2024-09-10. 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 2024-11-08. This does not confirm availability.

Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it reserved on 2018-05-09 and assigned (dated 2018-05-10) on 2018-05-11. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

ARIN's statistics show it reserved on 2018-05-09 and assigned (dated 2018-05-10) on 2018-05-11. ARIN removed its own pool record for this range as part of issuing it: the same report adds 192.107.1.0-192.107.1.255. The issuance is explained on that line.

The RIPE NCC's statistics now list it as 'available'; reissue not confirmed
The RIPE NCC's statistics show it reserved on 2014-04-17 and available on 2014-04-18. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2012-10-05, 560 days earlier. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Removed from active registration. The tracker found it by comparing the RIPE NCC's daily statistics. The RIPE NCC's statistics show it assigned (dated 1991-04-24) on 2012-10-04 and reserved on 2012-10-05. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC's current hold for IPv4 space applies to removals from 2014-03-26 on, and this one came earlier, so the tracker gives no estimate. This does not confirm availability.

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.
