Removed from active registration. The tracker found it by comparing AFRINIC's daily statistics. AFRINIC's statistics show it allocated (dated 2010-01-07) on 2013-12-26 and reserved on 2013-12-27. Public sources do not distinguish a voluntary return, revocation, or reclamation. AFRINIC publishes no fixed period for which it holds returned IPv4 space before reissuing it, so the tracker gives no estimate. 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.
