Frequently Asked Questions
Are these DNS records cached or live?
All queries are executed directly against authoritative nameservers in real time, reflecting live DNS propagation.
What is the difference between SPF and DMARC?
SPF declares which mail servers are authorized to send email on behalf of your domain, while DMARC instructs receivers on how to handle emails that fail SPF or DKIM authentication.
Why are CAA records important?
CAA (Certification Authority Authorization) records specify which Certificate Authorities are allowed to issue SSL/TLS certificates for your domain, preventing unauthorized certificate issuance.
