Summary

// analyst note
Routing counts and AS_PATH neighbours are a combined observation from route-views2 and route-views6 at 2026-11-03T14:00:00.000Z; neighbours are not verified peers or commercial relationships.

About this ASN.

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

AS1101 is an ASN assigned by ARIN in IANA’s registry; its operator and country are unknown from the supplied evidence. In the combined Route Views observation at 2026-11-03 14:00 UTC, across route-views2 and route-views6, it had 17 IPv4 prefixes and 3 IPv6 prefixes visible, representing an estimated 1,904,128 IPv4 addresses. This snapshot shows routing announcements at that time; it does not establish who operates the ASN or whether those routes are currently present.

The projection records 14 observed AS_PATH neighbours: AS1102, AS1103, AS1106, AS1680, AS6939, AS12552, AS12637, AS37100, AS57866, AS58511, AS64404, AS201616, AS214380, and AS215125. These are path adjacencies in the combined observation, not verified commercial peers, upstreams, or customer relationships. The count is an observation across both named collectors together, not a per-collector count.

For identification, compare the ASN and any candidate prefixes against the registry and routing data for the relevant time, then seek first-party documentation that explicitly links an organization to AS1101. Treat the listed neighbours as leads for examining paths, not proof of business relationships. For operational triage, check a fresh multi-vantage routing snapshot and the specific prefix origin before drawing conclusions; this single observation cannot establish present-day status, traffic prevalence, deployment, or safety.

Identity
IANA records AS1101 in the ARIN-allocated block; the operator is unknown from the supplied evidence.
Routing snapshot
At 2026-11-03 14:00 UTC, 17 IPv4 prefixes and 3 IPv6 prefixes were observed in the combined route-views2 and route-views6 observation.
Triage
14 AS_PATH neighbours were observed; these do not establish verified peers, upstreams, or commercial relationships.
