Every change the tracker has found, newest first. It covers ARIN from 2008-12-01, the RIPE NCC from 2010-04-23, APNIC from 2008-02-15, LACNIC from 2012-06-29 and AFRINIC from 2012-10-03.

ARIN's statistics now list it as 'available'; reissue not confirmed

ARIN's statistics show it reserved on 2013-10-06 and available on 2013-10-08. ARIN took it out of its reserved (held) records; its statistics now give it the status 'available'. The tracker saw it removed from registration on 2013-07-08, 91 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2013-10-08: Add 74.123.184.0-74.123.187.255), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2013-09-06. 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 allocated (dated 2010-03-25) on 2013-07-07 and reserved on 2013-07-09. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv4 space for 60 days before reissuing it, so the estimated hold end is 2013-09-06. This does not confirm availability.

No transfer record matches. ARIN's statistics show it not issued on 2010-03-24 and allocated (dated 2010-03-25) on 2010-03-26. (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.

RDAP lookups

Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
