    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns7.yahoo.com; only in the zone: ns4.yahoo.com. ns1.yahoo.com, ns2.yahoo.com, ns3.yahoo.com, ns4.yahoo.com, ns5.yahoo.com report NS ns1.yahoo.com ns2.yahoo.com ns3.yahoo.com ns4.yahoo.com ns5.yahoo.com.
    #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 6 IPv4 /24s and 4 IPv6 /48s.
  • ✓ 5 autonomous systems #11
    The nameservers are spread over: AS10880 (YAHOO-AN2 - Yahoo Holdings Inc., US): 4 addresses; AS23879 (YAHOO-INY - INY Edge site, US): 2 addresses; AS26101 (YAHOO-BF1 - Yahoo Holdings Inc., US): 1 address; AS36646 (YAHOO-NE1 - Yahoo Holdings Inc., US): 1 address; AS7280 (YAHOO-FC - Yahoo Holdings Inc., US): 2 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
  • i
    Partly IPv6
    These nameservers have no IPv6 address: ns4.yahoo.com, ns7.yahoo.com.

    TTLs: A 5m, MX 30m, NS 2d. The NS TTL at the parent is 1h and in the zone 2d; resolvers may use either.
  • ✓ No CNAME at the apex #33
    The zone apex has no CNAME record.

    Wildcard record
    A random name under the zone resolves, so there is a wildcard (*) record. Typos and non-existent hosts resolve too, which can confuse mail and certificate checks.
