ARIN's transfer log records a merger, acquisition or reorganization from SBO Group, Inc. (ARIN) to Fiserv Solutions, LLC (ARIN) on 2023-06-15 22:14 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.

No transfer record matches. ARIN's statistics show it reserved on 2019-01-14 and assigned (dated 2019-01-15) on 2019-01-16. The tracker saw this range released from hold on 2019-01-14 (216.151.33.0-216.151.33.255), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2019-01-14: Remove 216.151.33.0-216.151.33.255), so the before-and-after statistics may include it.

Part of the issuance reported the same day

ARIN's statistics show it reserved on 2019-01-14 and assigned (dated 2019-01-15) on 2019-01-16. ARIN removed its own pool record for this range as part of issuing it: the same report adds 216.151.33.0-216.151.33.255. The issuance is explained on that line. Another change to this range was reported the day before or after (2019-01-14: Remove 216.151.33.0-216.151.33.255), so the before-and-after statistics may include it.

ARIN-Issued lists it as "Remove", but ARIN's statistics show the same record before and after (reserved). Another change to this range was reported the day before or after (2019-01-15: Remove 216.151.33.0-216.151.33.255; 2019-01-15: Add 216.151.33.0-216.151.33.255), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2017-05-06. 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 2017-02-27) on 2017-03-06 and reserved on 2017-03-08. 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 2017-05-06. This does not confirm availability.

No transfer record matches. ARIN's statistics show it allocated (dated 2001-02-14) on 2017-02-26 and allocated (dated 2017-02-27) on 2017-02-28. The holder's record is the same before and after, so this is a change to the registration, not a change of holder.

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.

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.
