Hold estimate
Estimated hold end 2014-12-13. 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 2011-02-14) on 2014-10-13 and reserved on 2014-10-15. 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 2014-12-13. This does not confirm availability.

Inventory
Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it not issued on 2011-02-13 and allocated (dated 2011-02-14) on 2011-02-15. (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.

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.
