No transfer record matches. ARIN's statistics show it available on 2014-10-01 and allocated (dated 2014-10-02) on 2014-10-03. The tracker saw this range released from hold on 2014-09-15 (216.126.215.0-216.126.239.255), so it appears to have been issued again from ARIN's pool.

Hold estimate
Estimated hold end 2014-09-07. 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 1999-07-02) on 2014-07-08 and reserved on 2014-07-10. 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 2014-09-07. 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.
