ARIN-Issued

ARIN's statistics show it reserved on 2025-06-30 and allocated (dated 2025-07-01), allocated (dated 2025-07-02) on 2025-07-02. ARIN removed its own pool record for this range as part of issuing it: the same report adds 216.238.32.0-216.238.35.255, 216.238.40.0-216.238.43.255, 216.238.44.0-216.238.47.255, 216.238.48.0-216.238.51.255 and 3 more. The issuance is explained on those lines. Another change to this range was reported the day before or after (2025-07-02: Remove 216.238.36.0-216.238.39.255; 2025-07-02: Add 216.238.36.0-216.238.39.255), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2022-06-10. 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 2011-01-04) on 2022-04-10 and reserved on 2022-04-12. 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 2022-06-10. This does not confirm availability.

Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it not issued on 2011-01-03 and allocated (dated 2011-01-04) on 2011-01-05. (Until 2013-03-05, ARIN's statistics list only what's issued.) The tracker saw this range released from hold on 2010-12-02 (216.238.0.0-216.238.255.255), so it appears to have been issued again from ARIN's pool.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv4 range (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). A transfer between two registries is in both logs.

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.
