    #6
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only in the zone: ns2.geberit.de. ns.geberit.ch, ns.geberit.de, ns2.geberit.de report NS ns.geberit.ch ns.geberit.de ns2.geberit.de.
    #7
  • !
    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: ns.geberit.de (glue 193.99.99.33, zone 193.99.99.152). Update the glue at your registrar.
    #8
  • ✓ 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 2 IPv4 /24s and 0 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS3303 (SWISSCOM - Swisscom (Schweiz) AG, CH): 1 address; AS3320 (DTAG - Deutsche Telekom AG, DE): 2 addresses.
  • ✓ Nameserver names under 2 TLDs #12
    Nameserver names use the TLDs .ch, .de.
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
