No transfer record matches. LACNIC's statistics show it available on 2026-10-26 and allocated (dated 2017-12-22) on 2026-10-27. The new registration isn't dated near that day, so the tracker can't tell whether this is a new issuance. Another change to this range was reported the day before or after (2026-10-26: Removed 45.228.140.0/22), so the before-and-after statistics may include it.

Removed from active registration. The tracker found it by comparing LACNIC's daily statistics. LACNIC's statistics show it allocated (dated 2017-12-22) on 2026-10-25 and available on 2026-10-26. Public sources do not distinguish a voluntary return, revocation, or reclamation. LACNIC holds returned, revoked and reclaimed IPv4 space for 6 calendar months before reissuing it, so the estimated hold end is 2027-04-26. This does not confirm availability. Another change to this range was reported the day before or after (2026-10-27: Added 45.228.140.0/22), so the before-and-after statistics may include it.

Likely issued from LACNIC-controlled inventory

No transfer record matches. LACNIC's statistics show it available on 2017-12-21 and allocated (dated 2017-12-22) on 2017-12-22. The tracker saw this range released from hold on 2017-12-21 (45.228.140.0/22), so it appears to have been issued again from LACNIC's pool. Another change to this range was reported the day before or after (2017-12-21: Released 45.228.140.0/22), so the before-and-after statistics may include it.

LACNIC's statistics now list it as 'available'; reissue not confirmed

LACNIC's statistics show it reserved on 2017-12-20 and available on 2017-12-21. LACNIC moved it from its reserved (held) records to the status it calls 'available'. That is LACNIC's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2017-12-22: Added 45.228.140.0/22), so the before-and-after statistics may include it.
