What Is the Role of DNS in Website Performance?

How does a DNS provider affect the speed and reliability of a website? Can switching DNS improve performance?

DNS plays a critical role in translating domain names into IP addresses, which allows browsers to find your website. A faster DNS provider can reduce the time it takes for this translation, improving overall load times. Reliable DNS services also ensure uptime by mitigating outages with failover systems. To improve performance:

1. Use DNS providers with globally distributed servers (e.g., Cloudflare, Google Public DNS).
2. Look for features like DNS caching and optimization.
3. Monitor DNS response times and switch to faster providers if needed.
