ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics. ARIN's statistics show it allocated (dated 1998-10-26) on 2011-11-14 and not issued on 2011-11-16. (Until 2013-03-05, ARIN's statistics list only what's issued.) 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 2012-01-14. This does not confirm availability."}]},"arin_statistics_now":{"status":"allocated (dated 2012-06-14)"}}
