BGP-announced prefixes indexed in WhisperGraph · last refreshed
Whisper Internet Directory documents 1,412,498 BGP-announced IP prefixes — every CIDR block observed in the public BGP routing table. Each prefix has a canonical page at /prefix/<cidr> listing its announcing ASN, contained IP-address sample, active MOAS conflicts, and routing history.
How to find a prefix page
Append any CIDR-formatted prefix (e.g. 1.1.1.0/24) to /prefix/. The page is generated on first visit and cached at the edge for subsequent reads.
