ARIN's statistics show it reserved on 2024-03-31 and available, reserved on 2024-04-02. ARIN re-cut its own reserved records for this range; nothing was issued or returned. Another change to this range was reported the day before or after (2024-04-02: Add 167.253.144.0-167.253.147.255; 2024-04-02: Add 167.253.156.0-167.253.159.255), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2023-07-07. 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 2000-01-14) on 2023-05-07 and reserved on 2023-05-09. 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 2023-07-07. 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.
