ARIN-Issued says "Remove", but ARIN's statistics show it not issued on 2011-06-07 and allocated (dated 2011-06-08), not issued on 2011-06-09. (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. Another change to this range was reported the day before or after (2011-06-09: Add 209.54.128.0-209.54.159.255), so the before-and-after statistics may include it.

No transfer record matches. ARIN's statistics show it not issued on 2011-06-07 and allocated (dated 2011-06-07) on 2011-06-09. (Until 2013-03-05, ARIN's statistics list only what's issued.) The tracker saw this range released from hold on 2011-06-07 (74.118.240.0-74.118.247.255), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2011-06-07: Remove 74.118.240.0-74.118.247.255), so the before-and-after statistics may include it.

No transfer record matches. ARIN's statistics show it allocated (dated 2010-05-14) on 2011-06-07 and allocated (dated 2011-06-07) on 2011-06-09. (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 2011-12-08. 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 2010-07-06) on 2011-06-07 and not issued on 2011-06-09. (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 2011-12-08. This does not confirm availability.
