Problems

  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns1.ialloc.com (118.24.109.1): read udp 46.225.38.91:54701->118.24.109.1:53: i/o timeout.
    #14
  • ✗
    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns1.ialloc.com (2402:4e00:1700:7d00:0:9285:ffec:9d26): dial tcp [2402:4e00:1700:7d00:0:9285:ffec:9d26]:53: connect: connection refused; ns2.ialloc.com (115.159.66.63): dial tcp 115.159.66.63:53: connect: connection refused; ns2.ialloc.com (2402:4e00:1409:9f00:0:991f:7f1e:1de9): dial tcp [2402:4e00:1409:9f00:0:991f:7f1e:1de9]:53: connect: connection refused.

    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns1.ialloc.com (glue 115.159.66.63, 118.24.109.1, 2402:4e00:1700:7d00:0:9285:ffec:9d26, zone 118.24.109.1, 2402:4e00:1700:7d00:0:9285:ffec:9d26); ns2.ialloc.com (glue 115.159.66.63, 118.24.109.1, 2402:4e00:1409:9f00:0:991f:7f1e:1de9, zone 115.159.66.63, 2402:4e00:1409:9f00:0:991f:7f1e:1de9). Update the glue at your registrar.

    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
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: google (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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:ep@upai.com (needs yupoo.com._report._dmarc.upai.com). Ask the report provider to publish the record, or check the address.
