About this ASN.

Updated  ·  Confidence: Low  ·  4 sources  ·  How this page is checked

AS1121 is an ASN in the IANA block assigned by ARIN, with no IPv4 or IPv6 prefixes observed in the combined Route Views snapshot at 2026-11-03 14:00 UTC. This establishes its visibility in that snapshot only; it does not establish whether the ASN is active, who operates it, or whether it is legitimate.

The combined observation across route-views2 and route-views6 contains zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero AS_PATH neighbours. The empty neighbour sample does not establish an absence of commercial peers or upstreams. These figures are not separate per-collector counts.

For identification or troubleshooting, compare a relevant route observation against later snapshots and additional collectors, then check the origin ASN and complete AS_PATH for the specific prefix. Use registry assignment as allocation context only; confirm operator identity through first-party documentation before associating AS1121 with an organization or product.

Routing snapshot
No IPv4 or IPv6 prefixes were observed in the combined route-views2 and route-views6 observation at 2026-11-03 14:00 UTC.
Triage
Treat this as a time-bounded visibility result; check other snapshots and collectors for route changes.
Identity
IANA lists the ASN within the block assigned by ARIN; this does not identify an individual operator.
