About this ASN.

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

AS1236 is an ASN with no operator identity established by the supplied evidence. In the combined Route Views snapshot observed at 2026-11-03 14:00 UTC, route-views2 and route-views6 show four IPv4 prefixes, an estimated 1,024 IPv4 addresses, and zero IPv6 prefixes. This is a dated routing observation, not a claim about current announcements or deployment. The supplied evidence does not establish whether the ASN is active beyond that snapshot or who operates it.

IANA lists AS1236 in the 1–1876 resource as assigned by ARIN. This identifies the allocating regional registry for the block; it does not establish an individual assignment, organization, country, or network purpose. No first-party organizational history, product documentation, or website evidence is supplied, so those identity details remain unknown.

The combined observation records one AS_PATH neighbor, AS701. Treat that as a routing adjacency in this snapshot, not proof of a commercial peer, provider, upstream, or customer relationship. For identification, compare the ASN and observed prefixes against the timestamped routing data, then seek an explicit first-party statement linking an organization to AS1236 before assigning an operator or purpose. Zero observed IPv6 prefixes means none appeared in this snapshot, not that the ASN has no IPv6 allocation or deployment.

Identity
Operator and network purpose are unknown from the supplied evidence.
Routing snapshot
Four IPv4 prefixes and zero IPv6 prefixes were observed at 2026-11-03 14:00 UTC in the combined route-views2 and route-views6 observation.
Triage
One AS_PATH neighbor, AS701, is observed; this does not establish a commercial relationship or upstream.
