Problems

  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns1.nikon.net (66.11.133.20): read udp 46.225.38.91:58410->66.11.133.20:53: i/o timeout; ns2.nikon.net (66.11.133.21): read udp 46.225.38.91:36039->66.11.133.21:53: i/o timeout; ns3.nikon.net (65.51.14.217): read udp 46.225.38.91:59632->65.51.14.217:53: i/o timeout.

    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns1.nikon.net, ns2.nikon.net, ns3.nikon.net. nikns1.nikonusa.com, nikns2.nikonusa.com, nikns3.nikonusa.com report NS nikns1.nikonusa.com nikns2.nikonusa.com nikns3.nikonusa.com ns1.nikon.net ns2.nikon.net ns3.nikon.net.

  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Unusual SOA timers
    SOA · refresh 5m is outside 20m–1d. Current values: refresh 5m, retry 1m, expire 28d, negative TTL 5m.
    #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.

Problems

  • !
    No key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.
    #7
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mxa-00620203.gslb.pphosted.com, mxb-00620203.gslb.pphosted.com
    #11
  • !
    Subdomains unprotected (sp=none)
    DMARC · DMARC subdomain policy is sp=none, so spoofed mail from subdomains is not blocked. Consider sp=quarantine or sp=reject.
    #20
  • !
    Not configured
    TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
