Maintaining DNS Integrity & Resilience

Advanced DNS management involves more than just records; it requires proper zone hygiene and security hardening. This guide covers the advanced protocols available in BoostonCP.

1. Nameserver (NS) Synchronization

The NS Records define which servers are authoritative for your domain. BoostonCP automatically generates default NS records based on your system configuration. You can modify these to establish a custom white-label nameserver setup (e.g., ns1.yourbrand.com).

2. CAA & SRV Specialization

For enterprise-grade environments, BoostonCP supports specialized records:

  • CAA (Certificate Authority Authorization): Defines which CAs (like Let's Encrypt) are allowed to issue SSL certificates for your domain, preventing unauthorized certificate issuance.
  • SRV (Service Record): Critical for VOIP, XMPP, and specific mail protocols. Includes Weight and Port fields for precise service discovery.

3. Zone Deletion & Cleanup

If a domain is no longer hosted on the server, you can use the "Delete Zone" protocol. This permanently wipes the configuration from the server's DNS engine. Use this tool with caution, as it will immediately stop all traffic and email routing for that domain.

4. Propagation Verification

After saving records, you can verify their status using our built-in diagnostics or external tools like dig or nslookup. Remember that the TTL (Time To Live) value determines how long external caches will store your old records before checking for the new neural configuration.

CRITICAL ALERT: Incorrectly modifying NS Records can lead to global domain "blackout." Always double-check your nameserver designations before applying changes.
