Autonomous Systems indexed in WhisperGraph · last refreshed

Whisper Internet Directory documents 116,028 Autonomous Systems — every AS observed in the public BGP routing table. Each ASN has a canonical page at /asn/<number> listing its operator, country, peering ecosystem, routed prefix count, and active MOAS conflicts.

How to find an ASN page

Append the numeric ASN (without the AS prefix) to /asn/. The page is generated on first visit and cached at the edge for subsequent reads.
