Multiple nameservers provide redundancy
Nameserver Diversity
Nameservers on different networks improve resilience
Record Security
15/45 (33%)CAA Recordshigh
CAA restricts which CAs can issue certificates
→ Add CAA records to specify which Certificate Authorities are allowed to issue certificates for your domain. Example: 0 issue "letsencrypt.org"
SPF Record
SPF prevents email spoofing
DMARC Recordcritical
DMARC protects against phishing
→ Add a DMARC record at _dmarc.yourdomain.com. Example: v=DMARC1; p=quarantine; rua=mailto:dmarc@example.com
DKIM Presencenot checked
No DKIM key at the common selectors we try (default, google, selector1, selector2, k1, s1 and others). Many senders use their own selector names, so DKIM may still be set up. Not scored.
→ If this domain sends mail, look up the selector your email provider gave you with the DKIM checker (/dkim-checker).
Advanced Security
10/25 (40%)Mail Server Configurationmedium
Multiple MX records provide email redundancy
→ No MX records found. If you use email, configure MX records pointing to your mail server.
SOA Record Configuration
SOA timers that do not delay new names or expire secondaries (refresh 1h, retry 10m, expire 7d, SOA minimum 15m)
