Hold estimate
Estimated hold end 2027-01-03. 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 allocated (dated 2015-09-25) on 2026-11-03 and reserved on 2026-11-05. 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 2027-01-03. This does not confirm availability.

No transfer record matches. ARIN's statistics show it reserved on 2015-09-24 and assigned (dated 2015-09-25) on 2015-09-26. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

ARIN's statistics show it reserved on 2015-09-24 and assigned (dated 2015-09-25) on 2015-09-26. ARIN removed its own pool record for this range as part of issuing it: the same report adds 199.89.139.0-199.89.139.255. The issuance is explained on that line.
