About this ASN.

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

AS1563 is an ASN assigned by ARIN; a combined routing snapshot observed three IPv4 prefixes, no IPv6 prefixes, and one AS_PATH neighbor. The supplied evidence does not identify its operator, organization, country, products, or current operational status, so those details remain unknown. This snapshot is not enough to characterize the network as dormant or active beyond the routes observed at that time.

At 2026-11-06 20:00 UTC, the combined Route Views observation across route-views2 and route-views6 contained an estimated 131,328 IPv4 addresses and one observed neighbor, AS1554. That adjacency is an AS_PATH observation; it does not establish a verified peer, upstream, customer, or provider relationship. The counts describe the combined observation, not separate measurements from each collector.

For identification, compare the three observed IPv4 prefixes with the relevant registry records and seek first-party documentation that explicitly connects an organization to AS1563. Check a later routing snapshot to determine whether the announcements persist or change. Treat the single observed neighbor as a lead for route-path investigation, not evidence of a commercial relationship. No supplied evidence establishes security status or reputation.

Routing observation
Three IPv4 prefixes, zero IPv6 prefixes, and one AS_PATH neighbor were observed in the combined snapshot at 2026-11-06 20:00 UTC across route-views2 and route-views6.
Identity
Operator, organization, country, and website are unknown from the supplied evidence.
Triage
AS1554 is an observed AS_PATH neighbor only; the snapshot does not establish a verified peering or provider relationship, or security status.
