ARIN-Issued says "Remove", but ARIN's statistics show it not issued on 2011-12-20 and not issued on 2011-12-22. (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.

No transfer record matches. ARIN's statistics show it not issued on 2011-12-20 and allocated (dated 2011-12-21) on 2011-12-22. (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's transfer log records a transfer from Intalgent (ARIN) to Meddius, LLC (ARIN) on 2011-12-21 22:59 UTC. The registration changed hands; it is not a new allocation from ARIN. ARIN-Issued and ARIN's statistics don't show this change; only the transfer log records it.

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 2001-10-12) on 2011-12-20 and not issued on 2011-12-22. (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 2012-06-21. This does not confirm availability.
