AS1501

AS1501 is an ASN with 173 IPv4 prefixes observed in a combined Route Views snapshot; its operator and current operational purpose are unknown. The snapshot recorded no IPv6 prefixes, which means none were observed in that measurement, not that the ASN is inactive or dormant. The observation timestamp is 2026-11-03 14:00 UTC, across route-views2 and route-views6 collectively.

The combined data estimates 53,760 IPv4 addresses and records one AS_PATH neighbour, AS1555. That adjacency is a routing observation only: it does not establish a verified peer, an upstream, a customer relationship, or who operates either network. The registry evidence identifies ARIN as the allocating RIR for the IANA resource block containing AS1501; it does not establish an individual assignment, organization, country, or deployment location.

For triage, treat AS1501 as announcing IPv4 space in this dated snapshot, with its identity unresolved. If investigating a route, compare the specific prefix and origin against newer routing data and inspect the full AS_PATH and route details; do not infer operator identity or safety from this aggregate. The single snapshot and two-collector combined scope cannot establish present-day reachability, traffic use, legitimacy, or security status.

Routing exposure

173 IPv4 prefixes and an estimate of 53,760 IPv4 addresses were observed in the combined snapshot at 2026-11-03 14:00 UTC across route-views2 and route-views6.

IPv6 observation

No IPv6 prefixes were observed in that snapshot; this does not establish inactivity.

Identity and triage

Operator, purpose, country, and security status are unknown. AS_PATH neighbour AS1555 is not a verified peer or upstream.
