AS1357
No prefixes for this AS number were observed in the RouteViews RIB.
Summary
- // analyst note
- Routing data is the combined observation from route-views2 and route-views6 at 2026-11-03T14:00:00Z. No prefixes or AS_PATH neighbours were observed in this snapshot; this does not establish inactivity. IANA identifies ARIN as the allocating RIR for the encompassing AS-number block, not an individual assignment.
About this ASN.
AS1357 is an ASN with unknown operator and identity; no IPv4 or IPv6 prefixes were observed in the combined routing snapshot from route-views2 and route-views6 at 2026-11-03 14:00 UTC. This snapshot supports a limited routing statement, not a claim that the ASN is inactive or dormant.
The IANA AS-number registry places AS1357 in the block 1–1876 and identifies ARIN as the allocating regional internet registry. That block-level record does not establish an individual assignment, operator, country, or network purpose.
For identification, compare the ASN against a dated registry assignment record and first-party operator documentation that explicitly connects the organization to AS1357. For a specific route investigation, check additional timestamps and collectors, then inspect any matching announcements and their AS_PATH context. The current snapshot contains no observed prefixes or AS_PATH neighbours to assess.
- Routing snapshot
- Zero IPv4 prefixes, zero IPv6 prefixes, and zero observed AS_PATH neighbours in the combined route-views2 and route-views6 observation at 2026-11-03 14:00 UTC.
- Triage
- These zeros describe this snapshot only; they do not establish that AS1357 is dormant or inactive.
