ARIN-Issued
Remove 96.45.48.0-96.45.63.255
Inventory
Part of the issuance reported the same day

ARIN's statistics show it reserved on 2025-10-02 and allocated (dated 2025-10-03), available, reserved on 2025-10-04. ARIN removed its own pool record for this range as part of issuing it: the same report adds 96.45.48.0-96.45.51.255. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2024-04-05. 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 allocated (dated 2013-10-24) on 2024-02-04 and reserved on 2024-02-06. 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 2024-04-05. This does not confirm availability.

ARIN-Issued
Add 96.45.48.0-96.45.63.255

Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it available on 2013-10-23 and assigned (dated 2013-10-24) on 2013-10-25. The tracker saw this range released from hold on 2013-10-07 (96.45.48.0-96.45.63.255), so it appears to have been issued again from ARIN's pool.

ARIN-Issued
Remove 96.45.48.0-96.45.63.255
Inventory
ARIN's statistics now list it as 'available'; reissue not confirmed

ARIN's statistics show it reserved on 2013-10-06 and available on 2013-10-08. 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 2013-07-08, 91 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

Hold estimate
Estimated hold end 2013-09-06. 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 2009-10-07) on 2013-07-07 and reserved on 2013-07-09. 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 2013-09-06. This does not confirm availability.

ARIN-Issued
Add 96.45.48.0-96.45.63.255
Inventory
Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it not issued on 2009-10-06 and allocated (dated 2009-10-07) on 2009-10-08. (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.

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.
