Select a reliable DNS provider. Popular choices include Cloudflare, Amazon Route 53, and Google Cloud DNS. Ensure the provider has an API to automate DNS management.
| Area | Controls |
|------|----------|
| Authentication | Only authenticated WHMCS sessions can access the module; API tokens are stored encrypted using WHMCS’s Crypto class. |
| Authorization | Granular permission system: admin can manage all zones; client can only manage zones attached to their products. |
| Input Validation | Strict regex validation for each record type (e.g., IPv4: ^(\d1,3\.)3\d1,3$, domain names: RFC 1035). |
| Rate Limiting | Prevent abuse by limiting number of API calls per client per minute (configurable). |
| Audit Trail | Every API request (including source IP, timestamp, payload hash) is logged; immutable for at least 90 days. |
| GDPR / Data Retention | Ability to export a client’s DNS configuration in JSON and delete all personal data on request. |
| TLS Everywhere | All communication with the DNS back‑end uses HTTPS with certificate pinning if possible. |
| Backup & Recovery | Export zone files (BIND format) on demand; scheduled backups to off‑site storage (S3, Google Cloud). | dns manager for whmcs nulled 525 funny gewerbli link
| Extensibility Point | Example Use‑Case | |---------------------|------------------| | Back‑End Adapter Layer | Swap PowerDNS for Cloudflare without changing the WHMCS UI. | | Hook System | Add custom logic after a record is created (e.g., send a Slack notification). | | Plugin Marketplace | Offer premium addons like “Geo‑DNS”, “Dynamic DNS”, or “Failover IP”. | | Internationalisation (i18n) | UI strings stored in language packs (English, German, French, etc.). | | API Exposure | Provide a public REST endpoint so external tools (e.g., a custom control panel) can manage records via a token. | Select a reliable DNS provider
