What Is Preferred DNS Server?


Larry Thompson

A Preferred DNS server is an essential component of a computer network that helps translate domain names into IP addresses. DNS stands for Domain Name System, and it acts as a directory for the internet by mapping human-friendly domain names to their corresponding numeric IP addresses.

What is a DNS server?
A DNS server is a computer server that contains a database of public IP addresses and their associated domain names. When you enter a URL like “www.example.com” in your web browser, the DNS server is responsible for translating this domain name into an IP address that your computer can understand.

How does DNS resolution work?
When you type a web address in your browser, your computer sends a request to the DNS server to resolve the domain name. The DNS server then looks up its database and returns the corresponding IP address to your computer. This process is known as DNS resolution.

Preferred vs. Alternate DNS Server

In a typical computer network setup, there are two types of DNS servers: Preferred and Alternate. The Preferred DNS server is the primary server used for resolving domain names, while the Alternate (also known as Secondary) DNS server acts as a backup in case the Preferred server fails to respond.

Why use a Preferred DNS Server?
Using a Preferred DNS server offers several benefits. Firstly, it helps improve internet speed and performance by reducing the time taken to resolve domain names. Additionally, it can provide enhanced security features such as blocking malicious websites or filtering unwanted content.

How to set up a Preferred DNS Server?
Setting up a Preferred DNS Server on your computer or network router requires modifying the network settings. Here’s how you can do it:

  1. Open your network settings.
  2. Locate the TCP/IP settings or Internet Protocol (IP) settings.
  3. Select “Use the following DNS server addresses.”
  4. Enter the IP address of your Preferred DNS server.
  5. Save the settings and restart your computer or network device.

In conclusion, a Preferred DNS server plays a crucial role in translating domain names into IP addresses, allowing us to access websites and other resources on the internet. By understanding how it works and setting up a Preferred DNS server, you can enhance your internet experience with improved speed, security, and performance.
