Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2025-05-09. 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 2021-10-04) on 2025-03-09 and reserved on 2025-03-11. 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 2025-05-09. This does not confirm availability.

ARIN-Issued
Add 198.73.190.0-198.73.190.255
Inventory
Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it reserved on 2021-10-03 and allocated (dated 2021-10-04) on 2021-10-05. The tracker saw this range released from hold on 2021-10-01 (198.73.190.0-198.73.190.255), so it appears to have been issued again from ARIN's pool.

ARIN-Issued
Remove 198.73.190.0-198.73.190.255
Inventory
Part of the issuance reported the same day

ARIN's statistics show it reserved on 2021-10-03 and allocated (dated 2021-10-04) on 2021-10-05. ARIN removed its own pool record for this range as part of issuing it: the same report adds 198.73.190.0-198.73.190.255. The issuance is explained on that line.

Hold estimate
Estimated hold end 2020-09-04. 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 1993-05-13) on 2020-07-05 and reserved on 2020-07-07. 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 2020-09-04. 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.
