What Is a Good DNS Server?

A Domain Name System (DNS) server is an essential component of the internet infrastructure. It acts as a translator, converting human-readable domain names into machine-readable IP addresses. Every time you enter a website address into your browser, your device contacts a DNS server to obtain the corresponding IP address.

While most internet service providers (ISPs) provide their own DNS servers, there are several reasons why you might want to consider using an alternative DNS server. A good DNS server should offer enhanced security, improved performance, and additional features.


One of the primary concerns when choosing a DNS server is security.

In recent years, cyber threats have become increasingly sophisticated. Malicious actors can use DNS servers to redirect users to fake websites or launch phishing attacks. Therefore, it is essential to choose a DNS server that has robust security measures in place.


  • DNS Security Extensions (DNSSEC) is a technology that adds an extra layer of security to the DNS infrastructure.
  • It ensures that the responses from the DNS server are authentic and haven’t been tampered with by interceptors.
  • Look for a DNS server that supports DNSSEC to protect against spoofing and cache poisoning attacks.

Malware Blocking:

  • A good DNS server should have built-in malware blocking capabilities.
  • This feature helps prevent access to known malicious websites and protects your devices from malware infections.
  • Consider using a DNS server that actively blocks access to malicious domains and provides real-time threat intelligence updates.


Another crucial factor to consider is the performance of the DNS server.

A fast and reliable DNS server can significantly improve your overall internet experience by reducing latency and speeding up website loading times.

Global Network:

  • Choose a DNS server that operates a global network of servers strategically located around the world.
  • This ensures that DNS queries are resolved quickly, regardless of your geographical location.
  • A well-distributed network can help minimize latency and provide faster response times.

Anycast Routing:

  • DNS servers that use anycast routing deliver queries to the nearest available server in their network.
  • This technique helps reduce the distance between your device and the DNS server, resulting in faster response times.
  • Look for a DNS server that utilizes anycast routing for improved performance.

Additional Features

In addition to security and performance, some DNS servers offer additional features to enhance your browsing experience:

Ad Blocking:

  • Certain DNS servers have built-in ad-blocking capabilities.
  • By blocking ads at the DNS level, these servers can speed up website loading times and reduce distractions while browsing.

Content Filtering:

  • If you have children or want to restrict access to certain types of content, consider using a DNS server with content filtering options.
  • This feature allows you to block access to inappropriate websites or content categories such as adult content or social media platforms.


  • Some DNS servers prioritize user privacy and offer features like encrypted DNS queries.
  • Encrypted DNS helps protect your online activities from eavesdropping and enhances your overall privacy.

In conclusion, a good DNS server should provide robust security measures, improved performance, and additional features to enhance your browsing experience. Consider evaluating different DNS server options based on these criteria to find the one that best meets your needs.
