About this ASN.

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

AS1577 is an ASN with no IPv4 or IPv6 prefixes observed in the combined Route Views snapshot at 2026-11-06 20:00 UTC. The available evidence does not identify its operator, country, network type, website, or organizational status, so its identity remains unknown. This snapshot supports a limited routing observation; it does not establish whether the ASN is dormant, currently assigned to an operator, or used for any particular purpose.

The combined observation across route-views2 and route-views6 records zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero observed AS_PATH neighbours. The neighbour sample is empty. These are aggregate counts for the two named collectors at that timestamp, not separate counts for each collector. No neighbours were observed, so the evidence provides no basis for describing upstreams, verified peers, or commercial relationships.

For identification, compare the ASN with a dated registry or first-party record that explicitly links an organization to AS1577. For routing triage, inspect additional timestamped observations from independent collectors and check whether announcements appear over time. Treat a later route or registry match as evidence for that specific observation only; neither the current zero-route snapshot nor the ARIN allocation block establishes operator identity, deployment, traffic prevalence, or safety.

Observed routing
Zero IPv4 and IPv6 prefixes in the combined observation at 2026-11-06 20:00 UTC across route-views2 and route-views6.
Triage
No AS_PATH neighbours were observed; this snapshot alone does not establish dormant or inactive status.
Identity
Operator and organizational status are unknown from the supplied evidence.
