No transfer record matches. AFRINIC's statistics show it available on 2014-04-15 and assigned (dated 2014-04-15) on 2014-04-16. The tracker saw this range removed from registration on 2013-09-06 (196.6.174.0/23), so it appears to have been issued again from AFRINIC's pool.

Removed from active registration. The tracker found it by comparing AFRINIC's daily statistics. AFRINIC's statistics show it assigned (dated 2013-06-06) on 2013-09-06 and available on 2013-09-07. 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.

Removed from active registration. The tracker found it by comparing AFRINIC's daily statistics. AFRINIC's statistics show it assigned (dated 2012-10-04) on 2012-10-06 and not listed on 2012-10-07. Being gone from AFRINIC's statistics entirely can also mean it moved to another registry. 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.

No transfer record matches. AFRINIC's statistics show it available on 2012-10-04 and assigned (dated 2012-10-04) on 2012-10-05. It moved from AFRINIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by AFRINIC.

No transfer log has a transfer of any part of this IPv4 range.
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.
