AS1640

AS1640 is an ASN with observed IPv4 routing: a combined snapshot from route-views2 and route-views6 at 2026-11-06 20:00 UTC contained 18 IPv4 prefixes and no IPv6 prefixes. The available registry record identifies the allocating RIR as ARIN, but does not establish an organization, country, or current operator. This evidence does not support labeling AS1640 dormant or assigning it a security status.

The combined observation estimates 24,576 IPv4 addresses and records four AS_PATH neighbours: AS6461, AS6939, AS7018, and AS25645. These are route-path adjacencies; the snapshot does not verify direct peering, upstream, customer, or provider relationships. Counts describe the combined observation across both named collectors, not separate measurements for each.

For identification, compare the observed prefixes and paths with a current routing view and inspect registry or operator-published records that explicitly link an organization to AS1640. Treat the listed neighbours as leads for path investigation, not as proof of commercial relationships. A single timestamp and two collectors provide a limited view: routes absent from this observation should not be interpreted as inactive, and the prefix count alone says nothing about traffic, deployment, or safety.

Routing observation

18 IPv4 prefixes and 0 IPv6 prefixes were observed in the combined route-views2 and route-views6 snapshot at 2026-11-06 20:00 UTC.

Registry
