What Is a Default DNS Server?

A Default DNS Server refers to the DNS server that is automatically assigned to your computer or network by your internet service provider (ISP). It is the server that your computer uses to convert domain names into IP addresses, allowing you to access websites and other online resources.

The Role of DNS Servers

DNS servers play a crucial role in the functioning of the internet. When you enter a URL into your web browser, such as www.example.com, your computer needs to know the IP address associated with that domain name in order to establish a connection. This is where DNS servers come in.

DNS stands for Domain Name System. It is a decentralized system that translates human-readable domain names into machine-readable IP addresses. Without DNS servers, we would have to remember complex IP addresses for every website we want to visit.

Default DNS Servers and ISPs

When you connect to the internet through an ISP, they assign you an IP address, as well as one or more default DNS servers. These default DNS servers are typically provided by the ISP and are configured in your network settings automatically.

The main advantage of using default DNS servers is convenience. Most users don’t have to worry about configuring their own DNS settings because their ISP takes care of it for them.

Benefits of Default DNS Servers:

  • Simplicity: Using default DNS servers eliminates the need for manual configuration, making it easier for users.
  • Faster Access: Default DNS servers are usually located close to your geographical location, resulting in faster response times when accessing websites.
  • Reliability: ISPs typically maintain and update their DNS servers to ensure they are functioning optimally.

Drawbacks of Default DNS Servers:

  • Limited Customization: Default DNS servers may not offer advanced features or customization options that are available with other DNS providers.
  • Potential Privacy Concerns: Using default DNS servers provided by your ISP means they have access to your browsing data, which can raise privacy concerns for some users.
  • Possible Performance Issues: In some cases, default DNS servers provided by ISPs may experience congestion or outages, leading to slower internet access.

Changing the Default DNS Server

If you decide to change your default DNS server, you can manually configure the network settings on your computer or router. There are several alternative DNS providers available that offer enhanced features such as improved security, content filtering, and faster performance.

To change the default DNS server on a Windows computer, follow these steps:

  1. Open the Control Panel and navigate to Network and Internet > Network Connections.
  2. Right-click on your active network connection and select Properties.
  3. In the Properties window, select Internet Protocol Version 4 (TCP/IPv4) and click Properties again.
  4. In the next window, choose “Use the following DNS server addresses” and enter the desired DNS server addresses.
  5. Click OK to save the changes. You may need to restart your computer for the new settings to take effect.

Note that changing your default DNS server can have an impact on your internet experience, so it’s important to choose a reliable DNS provider and consider any potential consequences before making the switch.


A default DNS server is the server assigned to your computer or network by your ISP. It is responsible for translating domain names into IP addresses, allowing you to access websites on the internet.

While default DNS servers offer convenience and simplicity, they may have limitations in terms of customization and privacy. Changing the default DNS server is possible for those seeking alternative options with enhanced features or better performance.
