ARIN's transfer log records a transfer from Hosting Services, Inc. (ARIN) to Milan Public Utilities Authority (ARIN) on 2026-11-10 20:17 UTC. ARIN-Issued lists it as "Add" because the registration changed hands; it is not a new allocation from ARIN.

No transfer record matches. ARIN's statistics show it not issued on 2012-05-08 and allocated (dated 2012-05-09) on 2012-05-10. (Until 2013-03-05, ARIN's statistics list only what's issued.) It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.
