AS1557
No prefixes for this AS number were observed in the RouteViews RIB.
About this ASN.
AS1557 is an autonomous system number in IANA’s 1–1876 block, assigned by ARIN; its operator and organizational identity are Unknown from the supplied evidence. In the combined Route Views snapshot at 2026-11-06 20:00 UTC, no IPv4 or IPv6 prefixes were observed, so this snapshot provides no route-based basis for identifying an active network or assessing it for triage.
The combined observation across route-views2 and route-views6 records zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, zero observed peers, and an empty AS_PATH neighbour sample. These are results for that timestamp and those collectors only. They do not establish that AS1557 is dormant, unused, or absent from other routing data.
For identification, treat the ARIN entry as the allocating RIR information, not proof of an individual assignment or present-day operator. If investigating a route involving this ASN, compare its origin and path with other dated observations and seek an authoritative organization record explicitly linking the organization to AS1557. The supplied data supports no operator, country, product, website, reputation, or security conclusion.
- Identity
- IANA places AS1557 in the 1–1876 block assigned by ARIN; operator identity is Unknown.
- Routing snapshot
