Best Practices

• Appropriate TTLs — Lower for frequently changing records (300-900), higher for stable records (3600+)
• Backup zones — Export zones before major changes
• Test changes — Verify DNS resolution after updates
• SPF/DKIM/DMARC — Configure email authentication records
• CAA records — Limit certificate issuance to authorized CAs
