Problems

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns4-09.azure-dns.info: "Knot DNS 3.1.2.1770717641.d6b376aff". Hide or replace the version string.
    #17
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (30s), AAAA (30s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 2d; resolvers may use either.
