How Can We
Help You?

DNS management ensures domains resolve correctly for web, mail, and other services.

Steps:

1. Log in at www.lbreeze.net.
2. Go to DNS → Select your domain.
3. Add or edit records:
• A: IPv4 address for root or subdomains
• AAAA: IPv6 address
• CNAME: Alias for another hostname (do not use for root zone apex)
• MX: Mail exchange servers for email delivery
• TXT: Verification, SPF, DKIM, DMARC policies
4. Save and apply changes. Changes propagate based on TTL.

Best practices:

• Use a minimal TTL (e.g., 300 seconds) during migrations; increase after stability.
• SPF: Include lbreeze mail servers and sending services, avoid “+all”.
• DKIM: Enable for your domain to improve mail authenticity.
• DMARC: Start with p=none; monitor reports; then enforce p=quarantine or p=reject.

Troubleshooting:

• Conflicts arise if records exist in another DNS provider. Use one authoritative zone.
• Verify propagation using public resolvers. Ensure no CNAME exists at the zone apex where A/AAAA are required.
