Cypher and MCP

Reproduce this hostname's resolution chain against graph.whisper.security:

MATCH (h:HOSTNAME {name: "facebook.us"})-[:RESOLVES_TO]->(ip:IPV4)
      -[:ANNOUNCED_BY]->(ap:ANNOUNCED_PREFIX)-[:ROUTES]->(a:ASN)
OPTIONAL MATCH (a)-[:HAS_NAME]->(n:ASN_NAME)
RETURN ip.name AS ip, ap.name AS prefix, a.name AS asn, n.name AS network
LIMIT 20
