About this ASN.

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

AS1305 is an ASN in IANA’s 1–1876 block, which IANA identifies as assigned by ARIN; no live routing was observed for it in the combined Route Views snapshot at 2026-11-03 14:00 UTC. The available evidence does not identify an operator, country, or network type, so its organizational identity and role remain unknown.

Across route-views2 and route-views6 together, the snapshot contains zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero observed AS_PATH neighbours for AS1305. These figures describe that timestamp and combined collector scope only. They do not establish whether the ASN is inactive, unallocated, or used outside the observed routes.

For identification, compare a later routing snapshot and check authoritative registry records for an explicit ASN-to-organization link. If investigating a route attributed to AS1305, verify the announced prefix and AS_PATH at the time of the event; this snapshot offers no observed neighbours to use as a cross-check. Do not infer ownership or safety from the ARIN allocation-block label.

Observed status
Zero IPv4 and IPv6 prefixes and zero AS_PATH neighbours in the combined Route Views snapshot at 2026-11-03 14:00 UTC.
Identity
Operator, country, network type, and website are unknown from the supplied evidence.
Triage
This single snapshot does not establish inactivity or explain a route seen at another time; check event-time routing and authoritative registry records.
