Hold estimate
Estimated hold end 2027-01-08. 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 2021-04-01) on 2026-11-08 and reserved on 2026-11-10. 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 2027-01-08. This does not confirm availability.

No transfer record matches. ARIN's statistics show it reserved on 2021-03-31 and allocated (dated 2021-04-01) on 2021-04-02. The tracker saw this range released from hold on 2021-03-31 (45.42.204.0-45.42.255.255), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2021-03-31: Remove 45.42.204.0-45.42.255.255), so the before-and-after statistics may include it.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv4 range (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). A transfer between two registries is in both logs.
