No transfer record matches. ARIN's statistics show it not issued on 2011-01-29 and allocated (dated 2011-01-30) on 2011-01-31. (Until 2013-03-05, ARIN's statistics list only what's issued.) It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

ARIN-Issued says "Remove", but ARIN's statistics show it not issued on 2011-01-29 and not issued on 2011-01-31. (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.

Hold estimate
Estimated hold end 2011-07-30. 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 1999-12-10) on 2011-01-29 and not issued on 2011-01-31. (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 2011-07-30. This does not confirm availability.
