    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: gwa.fe.bosch.de, gwa2.fe.bosch.de.

  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only in the zone: ns1.fe.bosch.de, ns2.fe.bosch.de, ns3.fe.bosch.de, ns4.fe.bosch.de, ns5.fe.bosch.de, ns6.fe.bosch.de. gwa.fe.bosch.de, gwa2.fe.bosch.de, ns1.fe.bosch.de, ns2.fe.bosch.de, ns3.fe.bosch.de, ns4.fe.bosch.de, ns5.fe.bosch.de, ns6.fe.bosch.de report NS gwa.fe.bosch.de gwa2.fe.bosch.de ns1.fe.bosch.de ns2.fe.bosch.de ns3.fe.bosch.de ns4.fe.bosch.de ns5.fe.bosch.de ns6.fe.bosch.de.
    #7
  • ✓ No glue needed #8
    All nameservers are outside the zone, so no glue records are needed.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 8 IPv4 /24s and 7 IPv6 /48s.
  • ✓ 4 autonomous systems #11
    The nameservers are spread over: AS133466 (BOSCH-NET-AP - Robert Bosch GmbH, SG): 3 addresses; AS20940 (AKAMAI-ASN1 - Akamai International B.V., NL): 1 address; AS21342 (AKAMAI-ASN2 - Akamai International B.V., NL): 10 addresses; AS9183 (UNSPECIFIED - Robert Bosch Gesellschaft mit Beschraenkter Haftung, DE): 3 addresses.
  • i
    All nameserver names under .de
    All nameserver names are under one TLD, so a problem with that TLD also makes the nameservers unreachable. Some operators use names under two TLDs for extra resilience.
    #12
  • i
    Partly IPv6
    These nameservers have no IPv6 address: ns6.fe.bosch.de.
