AS1378 announces 11 IPv4 and 0 IPv6 prefixes and peers with 3 other networks.
Summary
- // analyst note
- The three entries in peers_sample are observed AS_PATH neighbours, not verified peers or upstreams.
About this ASN.
AS1378 is an ASN assigned by ARIN; its operator is unknown, and a routing snapshot observed 11 IPv4 prefixes and no IPv6 prefixes. The observation is from 2026-11-03 14:00 UTC, combined across the Route Views route-views2 and route-views6 collectors.
The combined snapshot estimates 13,568 IPv4 addresses and records three distinct AS_PATH neighbours: AS174, AS8057, and AS21947. These are observed path adjacencies only; they do not establish verified peering, upstream, customer or provider relationships. The snapshot does not identify who operates AS1378 or where it is deployed.
For identification or triage, compare the ASN and its announced prefixes with the specific address or route under investigation, then check a newer routing view for persistence and origin consistency. Treat this dated observation as a routing snapshot, not proof of present-day activity, ownership, traffic prevalence, or safety. The available evidence supports no security finding.
- Routing snapshot
- 11 IPv4 prefixes, zero IPv6 prefixes, and an estimate of 13,568 IPv4 addresses were observed at 2026-11-03 14:00 UTC across route-views2 and route-views6 combined.
