About this ASN.

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

AS1173 has no IPv4 or IPv6 prefixes observed in the combined Route Views snapshot at 2026-11-03 14:00 UTC; its operator and operational status are unknown. The snapshot contains zero observed AS_PATH neighbours. These measurements combine route-views2 and route-views6 and describe only that observation, not whether the ASN is inactive or used elsewhere.

IANA lists AS1173 in the 1–1876 resource block as assigned by ARIN. This identifies the allocating RIR for the block; it does not establish an individual assignment record, present-day operator, country, or deployment. No first-party organization or product evidence is supplied to connect an entity to this ASN.

For identification, compare a later routing snapshot and registry records that explicitly associate AS1173 with an organization. If investigating a reported route, check its origin ASN and timestamp against the exact prefix announcement; the current combined snapshot provides no prefix or neighbour to trace. Do not treat the zero counts here as evidence of dormancy, safety, or malicious use.

Routing observation
Zero IPv4 and IPv6 prefixes and zero AS_PATH neighbours in the combined route-views2 and route-views6 snapshot at 2026-11-03 14:00 UTC.
Identity
Operator and deployment status are unknown; the routing observation does not identify an operator.
Registry
IANA lists AS1173 in a resource block assigned by ARIN; this is not an individual assignment record.
Triage
Use a later timestamped route observation and an explicit registry or first-party ASN-to-organization link to investigate identity or reported announcements.
