Blast radius

Approximate count of dependent hostnames if AS680 disappeared from the routing table.

~1,621,967 hostnames depend on this network.Sampled from 10 prefixes, snapshot Thu, 21 May 2026 06:16:22 GMT.

MOAS / hijack watch

Prefixes routed by AS680 that another Autonomous System also announces. A non-empty list is one of the strongest BGP-hijack signals available without active probes.

No active MOAS conflicts. Every prefix announced by AS680 is unique to AS680 in the current routing snapshot.

Cypher and MCP

Reproduce the headline metric directly against graph.whisper.security:

MATCH (a:ASN {name: "AS680"})-[:HAS_NAME]->(n:ASN_NAME)
OPTIONAL MATCH (a)-[:HAS_COUNTRY]->(c:COUNTRY)
RETURN a.name AS asn, n.name AS operator, c.name AS country
