Learn more →Why Best Practices Matter
Following DNS best practices is crucial for several reasons:
- Security: Protect against DNS attacks like cache poisoning, DNS hijacking, and DDoS attacks.
- Reliability: Ensure consistent and reliable DNS resolution for your domains.
- Performance: Optimize DNS configuration for faster response times and reduced latency.
- Email Deliverability: Implement proper email authentication to improve deliverability and prevent spoofing.
- Compliance: Meet industry standards and regulatory requirements for DNS security.
Implementation Approach
Assessment
Begin by assessing your current DNS infrastructure using tools like DNS Health Check, DNSSEC Validator, and Email Authentication validators. Identify vulnerabilities, misconfigurations, and areas for improvement.
Planning
Develop a comprehensive plan for implementing best practices. Prioritize critical security measures, then address performance optimizations. Consider the impact of changes on your existing services.
Implementation
Implement changes incrementally, starting with non-production environments when possible. Follow the specific guidelines in each best practices section for detailed implementation steps.
Monitoring
Continuously monitor your DNS infrastructure for security threats, performance issues, and compliance with best practices. Regularly review logs and reports to identify potential problems.
Best Practice
Implement a regular schedule for reviewing and updating your DNS configurations. Technology and threats evolve rapidly, so staying current with best practices is essential for maintaining security and performance.
