  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: ns1.pearson.com, ns2.pearson.com; only in the zone: dns-amer-2.ptns.pearson.com, dns-apac-1.ptns.pearson.com, dns-emea-1.ptns.pearson.com. dns-amer-2.ptns.pearson.com, dns-apac-1.ptns.pearson.com, dns-emea-1.ptns.pearson.com, ns1.pearson.com, ns2.pearson.com report NS dns-amer-2.ptns.pearson.com dns-apac-1.ptns.pearson.com dns-emea-1.ptns.pearson.com.

  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

  • !
    Unusual SOA timers
    SOA · refresh 15m is outside 20m–1d; retry 15m should be shorter than refresh 15m. Current values: refresh 15m, retry 15m, expire 30d, negative TTL 15m.
    #23
  • !
    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.
