  • ✓ 5 nameservers #6
    Delegated to nic1.opera.com, nic2.opera.com, nic3.opera.com, nic4.opera.com, nic6.opera.com.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: nic1.opera.com, nic2.opera.com, nic3.opera.com, nic4.opera.com, nic6.opera.com.
  • ✓ 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 5 IPv4 /24s and 5 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS136189 (OPERA-AS-AP - Opera Software Technology (Beijing) Co., Ltd., CN): 2 addresses; AS21837 (OPERASOFTWARE - Opera Software Americas LLC, US): 4 addresses; AS39832 (NO-OPERA - Opera Norway AS, NO): 4 addresses.
  • i
    All nameserver names under .com
    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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
