  • ✗
    No nameserver responds
    Nameservers · None of the nameserver addresses answered: ns1.force9.net (195.166.128.16): read udp 46.225.38.91:41610->195.166.128.16:53: i/o timeout; ns1.plusnet.co.uk (195.166.128.17): read udp 46.225.38.91:42766->195.166.128.17:53: i/o timeout; ns2.force9.net (195.166.128.17): read udp 46.225.38.91:43115->195.166.128.17:53: i/o timeout; ns2.plusnet.co.uk (195.166.128.16): read udp 46.225.38.91:54379->195.166.128.16:53: i/o timeout.

    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: ns1.plusnet.co.uk, ns2.plusnet.co.uk.
    #7
  • !
    Nameservers in one network
    Delegation · all IPv4 addresses are in 195.166.128.0/24. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).
    #10
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    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

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • ✗
    No SPF record
    SPF · No SPF record was found for this domain. SPF is important for preventing email spoofing. Add an SPF record to specify which servers are authorized to send email for your domain.
    #6
  • !
    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
  • !
    No MX records
    MX · No MX records found. If this domain is used for email, add MX records to specify mail servers. If it never receives mail, publish a null MX ("MX 0 .").
    #9
  • !
    Report address not authorized
    DMARC · These report addresses are in another domain that has not agreed to receive your reports, so receivers will not send them: mailto:noc@plus.net (needs plus.com._report._dmarc.plus.net). Ask the report provider to publish the record, or check the address.
