  • !
    Expires in 24 days
    Registration · The registration expires on 2026-11-16. Make sure it is renewed.

  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ycodns01.yodobashi.com. ycodns01.yodobashi.com, ycodns51.yodobashi.com, yctdns51.yodobashi.com report NS ycodns01.yodobashi.com ycodns51.yodobashi.com yctdns51.yodobashi.com.
    #7
  • !
    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.
    #27
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1d; resolvers may use either.

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 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: ycteml12.yodobashi.com, ycteml11.yodobashi.com, ycoeml12.yodobashi.com, ycoeml11.yodobashi.com
    #11
  • !
    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:densan-data@yodobashi.co.jp (needs yodobashi.com._report._dmarc.yodobashi.co.jp). Ask the report provider to publish the record, or check the address.
    #29
  • !
    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.
