ARIN-Issued says "Remove", but ARIN's statistics show it not issued on 2010-12-05 and not issued on 2010-12-07. (Until 2013-03-05, ARIN's statistics list only what's issued.) The registry's pool records from that time aren't public, so the tracker can't tell what was removed.

Estimated hold end 2011-06-06. 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 assigned (dated 2008-11-09) on 2010-12-05 and not issued on 2010-12-07. (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 IPv6 space for 6 calendar months before reissuing it, so the estimated hold end is 2011-06-06. This does not confirm availability.
