DNS Records Guide

Understanding DNS record types and configuration

Essential DNS Record Types

  • A Record: Maps domain to IPv4 address (e.g., 192.0.2.1)
  • AAAA Record: Maps domain to IPv6 address
  • MX Record: Specifies mail servers for email delivery
  • TXT Record: Stores text data, used for SPF, DKIM, DMARC
  • CNAME Record: Creates alias to another domain
  • NS Record: Delegates subdomain to name servers
  • SOA Record: Contains zone authority information
  • CAA Record: Controls which CAs can issue certificates

DNS Best Practices

Proper DNS configuration is crucial for website availability and email delivery. Use multiple A records for redundancy, configure proper TTL values based on change frequency, implement CAA records to prevent unauthorized SSL certificates, and always test changes in a staging environment first. Monitor DNS propagation after changes and keep backup of your DNS configuration.
