Summary

// analyst note
RouteViews combined snapshot across route-views2 and route-views6 at 2026-11-01T00:00:00Z observed three IPv4 prefixes, zero IPv6 prefixes, an estimate of 512 IPv4 addresses, and two AS_PATH neighbours. These neighbours are not verified peers or upstreams.

About this ASN.

Updated  ·  Confidence: Low  ·  3 sources  ·  How this page is checked

AS1035 is an ASN with an unknown operator and country; a combined RouteViews snapshot observed three IPv4 prefixes and no IPv6 prefixes at 2026-11-01 00:00 UTC. This is a dated routing observation, not proof of current deployment or organizational identity.

The combined observation across route-views2 and route-views6 counted an estimated 512 IPv4 addresses and two distinct AS_PATH neighbours: AS7018 and AS19930. These adjacencies do not establish verified peers, upstreams, or commercial relationships. No IPv6 prefixes appeared in this snapshot; that absence does not establish inactivity.

IANA lists AS1035 in the resource range 1–1876 as assigned by ARIN. This identifies the allocating RIR for the block, not the recipient of an individual ASN assignment. No first-party evidence here identifies the operator, network purpose, website, or organizational status. For investigation, compare the ASN's announced prefixes and paths in later snapshots, then seek an authoritative registry record explicitly connecting AS1035 to an organization before assigning an identity. Treat the two observed neighbours as path clues only.

Routing snapshot
Three IPv4 prefixes and zero IPv6 prefixes observed in the combined RouteViews snapshot at 2026-11-01 00:00 UTC.
Identity
Operator and country are unknown from the supplied evidence.
Triage
Treat AS7018 and AS19930 as observed AS_PATH neighbours only; the snapshot does not establish provider or peer relationships.
