About this ASN.

Updated  ·  Confidence: Low  ·  4 sources  ·  How this page is checked

AS1649 had 61 IPv4 prefixes and one IPv6 prefix in the combined Route Views snapshot observed at 2026-11-06 20:00 UTC by route-views2 and route-views6; its operator and deployed purpose are unknown. The snapshot included one AS_PATH neighbor, AS27066. These observations support routing triage, but do not establish who operates the ASN or whether the observed routes correspond to a particular service or organization.

The 61 IPv4 prefixes are a count of distinct advertised prefixes in this observation. The estimate of 132,608 IPv4 addresses summarizes their address-space sizes; it is not a count of prefixes or evidence that every address is in use. The single sampled AS_PATH neighbor records an observed path adjacency, not a verified peering session, upstream, or customer relationship. For identification, compare the ASN and its prefixes with independently documented organization records, then check later routing snapshots for changes.

IANA lists the ASN in the range assigned by ARIN, which identifies the allocating RIR, not an individual assignment record.
