No transfer record matches. ARIN's statistics show it reserved on 2025-10-02 and allocated (dated 2025-10-03) on 2025-10-04. The tracker saw this range removed from registration on 2019-01-08 (199.164.174.0/24), so it appears to have been issued again from ARIN's pool.

ARIN-Issued
Remove 199.164.174.0-199.164.174.255
Inventory
Part of the issuance reported the same day

ARIN's statistics show it reserved on 2025-10-02 and allocated (dated 2025-10-03) on 2025-10-04. ARIN removed its own pool record for this range as part of issuing it: the same report adds 199.164.174.0-199.164.174.255. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2019-03-09. 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 assigned (dated 2012-08-16) on 2019-01-07 and reserved on 2019-01-09. 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 2019-03-09. This does not confirm availability.

Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it not issued on 2012-08-15 and assigned (dated 2012-08-16) on 2012-08-17. (Until 2013-03-05, ARIN's statistics list only what's issued.) The tracker saw this range released from hold on 2010-12-02 (199.164.174.0-199.164.174.255), so it appears to have been issued again from ARIN's pool.

Inventory effect unknown

ARIN-Issued says "Remove", but ARIN's statistics show it not issued on 2010-12-01 and not issued on 2010-12-03. (Until 2013-03-05, ARIN's statistics list only what's issued.) The registry's pool records from that time aren't public, so the tracker can't tell what was removed.

Hold estimate
Estimated hold end 2010-07-25. 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 1994-08-08) on 2010-05-25 and not issued on 2010-05-27. (Until 2013-03-05, ARIN's statistics list only what's issued.) 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 2010-07-25. This does not confirm availability.

Transfer records

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.
