ARIN's transfer log records a merger, acquisition or reorganization from Micfo, LLC. (ARIN) to U.S. Marshals Service in accordance with the Final Order of Forfeiture (ARIN) on 2024-05-08 22:10 UTC. The registration changed hands; it is not a new allocation from ARIN. ARIN-Issued and ARIN's statistics don't show this change; only the transfer log records it.

Hold estimate
Estimated hold end 2022-01-22. 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 2017-02-21) on 2021-11-22 and reserved on 2021-11-24. 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 2022-01-22. This does not confirm availability.

ARIN's transfer log records a merger, acquisition or reorganization from Fiber Galaxy (ARIN) to Micfo, LLC. (ARIN) on 2019-05-23 20:14 UTC.

Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it reserved on 2017-02-20 and allocated (dated 2017-02-21) on 2017-02-22. The tracker saw this range removed from registration on 2014-06-10 (206.223.224.0/19), so it appears to have been issued again from ARIN's pool.

Part of the issuance reported the same day

ARIN's statistics show it reserved on 2017-02-20 and allocated (dated 2017-02-21) on 2017-02-22. ARIN removed its own pool record for this range as part of issuing it: the same report adds 206.223.224.0-206.223.255.255. The issuance is explained on that line.

Hold estimate
Estimated hold end 2014-08-09. 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 2006-01-17) on 2014-06-09 and reserved on 2014-06-11. 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 2014-08-09. 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.
