What DNS Server Should a DNS Server Use?

When setting up a DNS server, one of the important decisions to make is determining which DNS server it should use. The choice of DNS server can have a significant impact on the performance, security, and reliability of your DNS infrastructure. In this article, we will explore different options for DNS servers and discuss their pros and cons.

DNS Servers

There are several popular DNS server software available today, each with its own strengths and weaknesses. Some of the commonly used DNS servers include:

  • Bind: Bind (Berkeley Internet Name Domain) is one of the most widely used open-source DNS servers. It is highly configurable and offers advanced features like zone transfers, dynamic updates, and security extensions like DNSSEC.
  • PowerDNS: PowerDNS is another popular open-source DNS server that focuses on scalability and high-performance.

    It supports various backends like SQL databases, LDAP directories, and even external APIs.

  • DNSMasq: DNSMasq is a lightweight DNS forwarder and DHCP server commonly used in small networks or home environments. It provides simple configuration options with caching capabilities.
  • Unbound: Unbound is a validating, recursive, and caching DNS resolver designed for high-performance environments. It emphasizes security features such as cryptographic authentication and anti-spoofing measures.

Considerations for Choosing a DNS Server

When deciding which DNS server to use for your own DNS server setup, there are several factors to consider:

1. Performance

A fast and responsive DNS server can greatly improve the overall performance of your network. Look for DNS servers that are known for their speed and low latency. Consider the server’s ability to handle high loads and its caching capabilities.

2. Security

Security is a critical aspect of any DNS infrastructure. Choose a DNS server that implements security features like DNSSEC (Domain Name System Security Extensions) to protect against DNS spoofing and cache poisoning attacks.

3. Reliability

A reliable DNS server is essential to ensure uninterrupted access to your domain names. Look for servers that offer features like redundancy, failover mechanisms, and support for multiple transport protocols.

4. Scalability

If you anticipate an increase in traffic or the number of domain names, choose a DNS server that can scale accordingly. Consider how easily the server can handle larger zone files and increased query rates without compromising performance.


Choosing the right DNS server for your own DNS setup requires careful consideration of various factors such as performance, security, reliability, and scalability. Each DNS server has its own strengths and weaknesses, so it’s important to evaluate your specific requirements before making a decision. Whether you opt for Bind, PowerDNS, DNSMasq, Unbound, or any other DNS server software, ensure that it aligns with your needs and provides the necessary features to support your network infrastructure.
