Summary

// analyst note
Combined Route Views snapshot observed one IPv4 prefix and no IPv6 prefixes at 2026-11-06 20:00 UTC across route-views2 and route-views6. AS11260 is an AS_PATH neighbour, not a verified peer or provider relationship.

About this ASN.

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

AS1634 is an ASN whose operator is unknown; a combined Route Views observation recorded one IPv4 prefix and no IPv6 prefixes at 2026-11-06 20:00 UTC. This is a snapshot from route-views2 and route-views6, not a measure of current activity beyond that observation. The IANA registry identifies the ASN as assigned by ARIN within resource block 1–1876, but that block-level entry does not identify an individual assignment or operator.

The combined observation estimates 256 IPv4 addresses and records one distinct AS_PATH neighbour, AS11260. An AS_PATH adjacency alone does not establish a direct commercial peer, upstream, customer relationship, or shared organization. The snapshot does not establish who operates the ASN, where it is deployed, or whether its observed route is legitimate or harmful.

For identification, compare the ASN and any associated prefix with the specific route and timestamp under investigation, then inspect the observed AS_PATH and corroborate attribution through authoritative registry or first-party records. Do not infer operator identity from the ARIN allocation block or treat the single observed prefix as proof of a broader network footprint. Zero IPv6 prefixes means none were observed in this combined snapshot, not that the ASN has no IPv6 deployment at other times.

Identity
Operator and organization are unknown from the supplied evidence.
Observed routing
One IPv4 prefix, zero IPv6 prefixes, and an estimate of 256 IPv4 addresses were present in the combined observation at 2026-11-06 20:00 UTC across route-views2 and route-views6.
Neighbour
AS11260 is the sole sampled AS_PATH neighbour; this does not establish a peering or provider relationship.
Triage
Use the route and timestamp as investigation leads, and corroborate attribution independently; this snapshot does not establish safety or malicious use.
