About this ASN.

Updated  ·  Confidence: Low  ·  4 sources  ·  How this page is checked

AS1252 is an ASN assigned by ARIN, with nine IPv4 prefixes observed in a combined Route Views snapshot; its operator is unknown from the supplied evidence. This is a dated routing observation, not confirmation of who operates the ASN or whether it is currently deployed beyond that snapshot.

At 2026-11-03 14:00 UTC, the combined observation from collectors route-views2 and route-views6 contained nine IPv4 prefixes, an estimated 7,936 IPv4 addresses, and zero IPv6 prefixes. Two AS_PATH neighbours were observed: AS3356 and AS7896. These adjacencies do not establish verified peering, upstream, or customer relationships.

For identification, compare the ASN and its announced prefixes against a separately verified organization record before attributing ownership. If investigating a particular address, first check whether it falls within one of the observed IPv4 prefixes, then assess the relevant prefix and route at the time in question. The zero IPv6 count describes this snapshot only; it does not show that AS1252 is inactive or lacks IPv6 announcements at other times.

Identity
AS1252 is assigned by ARIN; an operator is not identified in the supplied evidence.
Routing snapshot
At 2026-11-03 14:00 UTC, nine IPv4 prefixes and zero IPv6 prefixes were observed in the combined route-views2 and route-views6 observation.
Observed neighbours
AS3356 and AS7896 appeared as AS_PATH neighbours; this does not verify commercial relationships.
Triage
Treat counts as a timestamped routing view, not proof of ownership, current deployment, safety, or inactivity.
