About this Autonomous System

AS36692 identifies an 16-bit Autonomous System on the public internet. Autonomous Systems are independently administered networks — typically ISPs, hosting providers, large enterprises, or content delivery networks — that exchange traffic with each other using the Border Gateway Protocol (BGP).

This particular AS is registered to Cisco OpenDNS, LLC. ASN registration data comes from the regional internet registries (ARIN, RIPE NCC, APNIC, LACNIC, AFRINIC) and is updated as allocations change.

For deeper BGP context — including announced prefixes, peering relationships, and historical routing changes — Hurricane Electric's BGP toolkit and bgp.tools are the standard references.

What you can do with this information

  • Identify the operator behind a suspicious IP — combine ASN with WHOIS for full registry context.
  • Detect bot or hosting traffic — ASNs from cloud providers (AWS, DigitalOcean, OVH) signal automated traffic versus residential ISPs.
  • Report abuse — use the abuse email above to file complaints against IPs under this AS.
  • Read more about how ASNs work.
