What Should Be Preferred DNS Server?


Heather Bennett

DNS (Domain Name System) is an essential component of the internet infrastructure that helps translate human-friendly domain names into IP addresses that computers can understand. When you connect to a website, your device uses a DNS server to resolve the domain name and retrieve the corresponding IP address.

There are two types of DNS servers: the preferred DNS server and the alternate DNS server. The preferred DNS server is usually provided by your internet service provider (ISP) and is automatically configured on your device. However, there may be situations where you may want to change your preferred DNS server for various reasons.

Why Consider Changing Your Preferred DNS Server?

Changing your preferred DNS server can offer several benefits, including:

  • Improved Performance: Some third-party DNS servers, such as Google Public DNS or OpenDNS, are known for their faster response times. By switching to one of these servers, you can potentially reduce the time it takes for your device to resolve domain names.
  • Better Security: Certain DNS servers offer additional security features such as malware blocking or phishing protection.

    These servers can help protect you from accessing malicious websites or being redirected to fake websites.

  • Bypassing Restrictions: In some cases, your ISP may block access to certain websites or impose restrictions on browsing speed. By using an alternative DNS server, you may be able to bypass these restrictions and access blocked content.

Choosing the Right Preferred DNS Server

When selecting a preferred DNS server, consider the following options:

1. Google Public DNS

Google Public DNS is a popular choice among users due to its reliability and fast response times. It provides enhanced security features and supports both IPv4 and IPv6 addresses.

2. OpenDNS

OpenDNS is another widely used DNS service that offers additional features such as content filtering and parental controls. It provides customizable options for blocking specific types of websites or categories.

3. Cloudflare DNS

Cloudflare DNS is known for its emphasis on privacy and security. It supports DNS over HTTPS (DoH) and DNS over TLS (DoT), which encrypt your DNS queries, making it harder for third parties to intercept your data.

Changing Your Preferred DNS Server

To change your preferred DNS server, follow these steps:

  1. Open the Control Panel on your device.
  2. Select “Network and Internet” or “Network and Sharing Center. “
  3. Click on “Change adapter settings.

  4. Right-click on your active network connection and select “Properties. “
  5. Scroll down to the “Internet Protocol Version 4 (TCP/IPv4)” or “Internet Protocol Version 6 (TCP/IPv6)” option, depending on your network configuration.
  6. Select the option to “Use the following DNS server addresses. “
  7. Enter the IP addresses of your preferred DNS server(s) in the designated fields.
  8. Click “OK” to save the changes.


While the default preferred DNS server provided by your ISP works fine for most users, there are valid reasons to consider changing it. By opting for a faster, more secure, or unrestricted alternative, you can potentially enhance your browsing experience.

Remember to choose a reliable DNS server and follow the appropriate steps to change it on your device.
