About this ASN.

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

A combined Route Views snapshot from route-views2 and route-views6 at 2026-11-06 20:00 UTC recorded zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero AS_PATH neighbours for AS1593. Neighbours here mean AS_PATH adjacencies, not commercial peers or upstreams. To verify routing visibility, compare later snapshots; this observation alone does not establish whether the ASN is inactive.

IANA places AS1593 in resource block 1-1876, assigned by ARIN. Operator, organization, and country: Unknown. This block-level registry entry does not identify an individual assignment or present-day holder.

For identification, compare a later routing snapshot and consult authoritative registration records for an explicit AS1593-to-organization link. If investigating a particular network, verify its prefix and origin in contemporaneous routing data rather than inferring association from the ASN number. The observed zero counts and empty neighbour sample provide no basis for security or reputation conclusions.

Identity
Operator, organization, and country are Unknown.
