No transfer record matches. LACNIC's statistics show it reserved on 2018-06-17 and assigned (dated 2018-06-18) on 2018-06-18. It moved from LACNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by LACNIC.

Hold estimate
Estimated hold end 2013-05-03. 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 1996-05-07) on 2013-03-03 and not listed on 2013-03-05. (Until 2013-03-05, ARIN's statistics list only what's issued.) Being gone from ARIN's statistics entirely can also mean it moved to another registry. 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 2013-05-03. 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.
