Likely issued from RIPE NCC-controlled inventory
No transfer record matches. The RIPE NCC's statistics show it available on 2019-11-24 and allocated (dated 2019-11-25) on 2019-11-25. It moved from the RIPE NCC's unissued pool to an active registration dated around that day, so it appears to be newly issued by the RIPE NCC.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2012-04-22. 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 assigned (dated 1995-09-21) on 2012-02-21 and not issued on 2012-02-23. (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 IPv4 space for 60 days before reissuing it, so the estimated hold end is 2012-04-22. This does not confirm availability.

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.
