Problems

  • !
    Nameservers in one network
    Delegation · all IPv4 addresses are in 5.8.68.0/24; all IPv6 addresses are in 2a03:90c0:999f::/48. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).
    #10
  • !
    Unusual SOA timers
    SOA · refresh 15m is outside 20m–1d; expire 1d is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 15m, retry 10m, expire 1d, negative TTL 10m.
    #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 DMARC record
    DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.
    #5
  • !
    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: mail.worldoftanks.com, mailbox.wargaming.net
    #11
  • !
    Hosts are CNAMEs
    MX · MX records must point to a host name with A/AAAA records, not to a CNAME: mail.worldoftanks.com -> mailbox.wargaming.net
    #22
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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.
