ARIN-Issued says "Remove", but ARIN's statistics show it not issued on 2011-11-10 and not issued on 2011-11-12. (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 2011-11-10 and allocated (dated 2011-11-11) on 2011-11-12. (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.

No transfer record matches. ARIN's statistics show it not issued on 2011-11-10 and assigned (dated 2011-11-11) on 2011-11-12. (Until 2013-03-05, ARIN's statistics list only what's issued.) The tracker saw this range released from hold on 2011-11-10 (204.145.210.0-204.145.210.255), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2011-11-10: Remove 204.145.210.0-204.145.210.255), so the before-and-after statistics may include it.

No transfer record matches. ARIN's statistics show it assigned (dated 1999-01-13) on 2011-11-10 and assigned (dated 2011-11-11) on 2011-11-12. (Until 2013-03-05, ARIN's statistics list only what's issued.) The registration was replaced with one for a different holder record, and public sources don't say why (a transfer not yet logged, a return and reissue, or an organization record change).

Hold estimate
Estimated hold end 2012-05-11. 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 2006-12-08) on 2011-11-10 and not issued on 2011-11-12. (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 2012-05-11. This does not confirm availability.
