About this ASN.

Updated  ·  Confidence: Medium  ·  5 sources  ·  How this page is checked

AS1003 is identified by its website as the ASN used by andrewnet production, and a combined Route Views snapshot observed 2 IPv4 prefixes and 11 IPv6 prefixes on 2026-10-31 at 00:00 UTC. The snapshot covers route-views2 and route-views6 together; it records 512 IPv4 addresses and 10 distinct AS_PATH neighbours. This is a dated routing observation, not a real-time status guarantee.

The first-party site distinguishes andrewnet production on AS1003 from andrewnet experimental on AS211562. It also lists peering locations in North Kansas City, Clifton, and Ashburn, and four Internet exchange connections, including a 40G Kansas City Internet Exchange connection. These published network details describe the site’s stated setup; they do not establish that any particular listed prefix uses a location, exchange, or service.

For triage, treat the ten observed neighbours as path adjacencies rather than confirmed peers, providers, or customers. Compare the observed prefixes and origins with the specific route or event under investigation, and check a fresh routing view before drawing conclusions about current reachability. The peering policy says traffic should be destined only for prefixes announced by andrewnet or its downstreams, and says prefixes may be withdrawn without prior notice.

IANA identifies the encompassing ASN block as assigned by ARIN; this does not establish an individual assignment record.

Routing observation
On 2026-10-31 at 00:00 UTC, the combined route-views2 and route-views6 snapshot observed 2 IPv4 prefixes and 11 IPv6 prefixes for AS1003.
Identity
The AS1003 site identifies andrewnet production as based on AS1003; operator identity beyond that statement is Unknown.
Triage
Ten observed AS_PATH neighbours are routing adjacencies only; validate the specific route and consult a fresh view for current reachability.

Neighbours observed by RouteViews at 2026-11-06, lowest ASN first. Relationships are inferences from the CAIDA AS Relationships Dataset, 2026-08-01, and establish no commercial arrangement; a dash means the inference did not resolve.
