ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics. ARIN's statistics show it allocated (dated 2009-02-13) on 2011-04-28 and not issued on 2011-04-30. (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 ASNs for 6 calendar months before reissuing them, so the estimated hold end is 2011-10-29. This does not confirm availability."}]},"arin_statistics_now":{"status":"assigned (dated 2025-02-11)"}}
