No transfer record matches. ARIN's statistics show it reserved on 2019-12-18 and assigned (dated 2019-12-19) on 2019-12-20. The tracker saw this range released from hold on 2019-12-17 (199.102.248.0-199.102.251.255), so it appears to have been issued again from ARIN's pool.

ARIN-Issued
Remove 199.102.248.0-199.102.251.255
Inventory
Part of the issuance reported the same day

ARIN's statistics show it reserved on 2019-12-18 and assigned (dated 2019-12-19) on 2019-12-20. ARIN removed its own pool record for this range as part of issuing it: the same report adds 199.102.248.0-199.102.251.255. The issuance is explained on that line.

ARIN-Issued lists it as "Remove", but ARIN's statistics show the same record before and after (reserved).

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2017-10-07. 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 2011-03-17) on 2017-08-07 and reserved on 2017-08-09. 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 2017-10-07. This does not confirm availability.

ARIN-Issued
Add 199.102.248.0-199.102.251.255
Inventory
Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it not issued on 2011-03-16 and assigned (dated 2011-03-17) on 2011-03-18. (Until 2013-03-05, ARIN's statistics list only what's issued.) It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

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.
