ARIN's transfer log records a transfer from VISTABEAM (ARIN) to HyperFiber (ARIN) on 2025-04-09 10:51 UTC. ARIN-Issued lists it as "Add" because the registration changed hands; it is not a new allocation from ARIN.

Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it available on 2014-06-08 and allocated (dated 2014-06-09) on 2014-06-10. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

ARIN's statistics show it available on 2014-06-08 and allocated (dated 2014-06-09) on 2014-06-10. ARIN removed its own pool record for this range as part of issuing it: the same report adds 104.37.8.0-104.37.15.255. The issuance is explained on that line.

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.
