About this ASN.

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

AS1600 is an ASN assigned through ARIN; its operator and organizational identity are unknown from the available evidence. In the combined Route Views snapshot observed at 2026-11-06 20:00 UTC, the ASN appeared with 171 IPv4 prefixes and 7 IPv6 prefixes. This is evidence of routing at that observation time, not a measure of traffic or proof of who operates the network.

The same combined snapshot records an estimate of 197,120 IPv4 addresses and one AS_PATH neighbour, AS27066. An AS_PATH neighbour is an observed route adjacency; it does not establish a verified peering relationship, an upstream, or a customer or provider relationship. The supplied evidence does not establish the network’s country, network type, website, or security status.

For identification, compare the relevant route’s origin and AS_PATH with this dated observation, then check a newer routing view and authoritative registration records before associating the ASN with an organization. Treat differences across times as changes in observed routing; this single snapshot cannot establish that an absent route is inactive or explain who announced it.

Identity
AS1600 is assigned through ARIN; operator identity is unknown from supplied evidence.
Routing observation
171 IPv4 prefixes and 7 IPv6 prefixes in the combined Route Views observation at 2026-11-06 20:00 UTC.
Triage
Routing was observed at that snapshot; it does not establish traffic, ownership, legitimacy, or security status.
Observed neighbour
AS27066 appears as the sole sampled AS_PATH neighbour; this does not verify a peering or commercial relationship.
