No transfer record matches. The RIPE NCC's statistics show it available on 2010-05-07 and allocated (dated 2009-04-28) on 2010-05-08. The new registration isn't dated near that day, so the tracker can't tell whether this is a new issuance. Another change to this range was reported the day before or after (2010-05-07: Removed 80.246.48.0/20), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Removed from active registration. The tracker found it by comparing the RIPE NCC's daily statistics. The RIPE NCC's statistics show it allocated (dated 2009-04-28) on 2010-05-06 and available on 2010-05-07. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC's current hold for IPv4 space applies to removals from 2014-03-26 on, and this one came earlier, so the tracker gives no estimate. This does not confirm availability. Another change to this range was reported the day before or after (2010-05-08: Added 80.246.48.0/20), so the before-and-after statistics may include it.

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.
