Over the past two decades, technological developments have dramatically increased internet speeds.Broadband and fiber connections create lightning-fast networks, where even high-definition media loads in seconds.

That's not to say there isn't room for improvement.Changing your DNS settings is often considered one of the easiest ways to optimize your internet speed.So let's see how DNS works and how to change your DNS settings.


What is DNS?

When you enter a website's URL into your browser, it needs to be translated into the website's IP address to send and receive data.The Domain Name System (DNS) is the equivalent of a digital phone book, providing a number (IP address) for a given name (URL).

For example, if you type a URL into your browser, the DNS server will translate it into an IP address.With over a billion websites currently online, maintaining such a large list is not practical.So instead, your DNS server stores a cache for a series of websites.

If you try to visit a website that is not already cached, your DNS server will request the entry from another server.Your default DNS server may be provided by your ISP and is not guaranteed to be the best performing server.

How does your location affect DNS speed?

The infrastructure that supports the Internet is a series of copper and fiber optic cables that connect servers around the world.Data travels through these cables in the form of electromagnetic waves whose speed is limited to the speed of light.While we can't do anything to increase this speed, we can reduce the distance these waves travel.

If a DNS server is far away from you, your browsing speed will suffer.However, the reality of the Internet is much more complex than simple distance calculations.Google Public DNS is one of the most popular DNS server alternatives and uses two IP addresses ( and

These are called anycast addresses, and multiple servers around the world respond to requests for these addresses.The servers that respond to requests change throughout the day, depending on network conditions and traffic.It is consistently rated as one of the fastest DNS servers, despite returning your queries from servers all over the world.

They do this by partnering with content delivery networks (CDNs) to append location data to DNS requests.In most cases, if you're going to use a Canadian DNS server, the CDN will think you're in Canada.

This affects loading speed, and the content you see will be optimized for Canadian audiences. CDNs have become essential to the functioning of the internet, and they are a critical component of whether you can actually break the internet.

Does changing your DNS improve speed?


When planning a trip with Google Maps, you'll see several different travel options.Some routes will take less time, even if they cover a greater distance.This can be due to many factors such as traffic, transit variations and average speed.

When choosing a DNS server to increase your internet speed, you will face a similar set of factors.Choosing the most favorable path is called route optimization.Some DNS servers, such as those provided by ISPs, will experience heavy traffic, especially during peak periods.

Some servers have outdated records, or route your data inefficiently.The complex interplay between servers and connections makes routing optimization an integral part of improving your internet speed.Your ISP's DNS servers may be nearby.However, their one-size-fits-all approach is unlikely to give you the best performance.

At this time, like Google'sNamebenchSuch tools come in handy.It offers free speed tests to help you find the fastest DNS to optimize your internet speed. Namebench analyzes your connection and recommends the best DNS server specifically tailored for you.

Namebench isn't your only option; there are other ways to find the fastest DNS to optimize your internet speed.Also, DNS doesn't just determine speed.You can choose a specific DNS provider to improve your online safety and security.

While your ISP may have its own DNS servers, it may not be the fastest option.Instead, you'll want to change your operating system's DNS settings.There are three leading alternative DNS providers; Google DNS,OpenDNSCloudflare DNS.We have access to Google DNS andCloudflare DNSA comparison was made to see which provider provided the fastest results, but you will experience an increase in speed and security by switching from the default DNS to these alternative providers.

How to Change DNS Settings on Windows 10 and Windows 11


Windows 10:

1. Press Win + X to open the Power User menu and select Network Connections.

2. Under Advanced Network Settings, select the Change Adapter option.

3. In the new window showing your available network devices, right-click your Internet-connected device and select Properties.

Windows 11:

1. Press Win + X to open the Power User menu and select Network Connections.

2. Select Advanced Network Settings > More Network Adapter Options.

3. In the new window showing your available network devices, right-click your Internet-connected device and select Properties.

From here, the process of changing DNS settings is the same for both Windows 10 and Windows 11.

Highlight the option titled Internet Protocol Version 4 (TCP/IPv4) and click Properties.Browse to the "Use the following DNS server addresses" option.

In this area, enter the following IP addresses, depending on which DNS provider you want to use:

Google DNS:,

Cloudflare IPv4:,

OpenDNS: 208.67. 222.222, 208.67. 220.220

Once entered, click OK to save these settings.You will be returned to the "Properties" menu.From here, select Internet Protocol Version 6 (TCP/IPv6), then click Properties.Now you can repeat the process for IPv6 DNS servers:

Google DNS: 2001:4860:4860::8888, 2001:4860:4860::8844

Cloudflare IPv6: 2606:4700:4700::1111, 2606:4700:4700::1001

OpenDNS: 2620:119:35::35, 2620:119:53::53

Click "OK" to save your IPv6 DNS settings.You can then close all settings windows and go back to your normal internet browsing.Once you click to confirm these settings, you will start using your new DNS server.

How to Change DNS Settings on MacOS

The need for DNS speed

While there is no magic bullet for increasing your internet speed, there are many smaller tweaks and improvements you can make.Together, these improvements increase your overall internet speed.

The DNS server you choose will play an important role in this process.
