Change Your DNS Server Settings, Get Faster Internet

The Domain Name System, also known as a DNS Server, serves as the phonebook of the internet. It’s used to match website and domain hostnames to their corresponding IP addresses. Usually, by default, these servers are set by your broadband provider, but you can change them to improve your internet connection.

Changing a DNS server may seem daunting, especially for the unfamiliar. However, it’s actually not as difficult as you think. Simply follow these few steps and see a boost in your internet speed.

How does a DNS server work?

Whenever you search for a domain name in your browser, it’s responsible for finding the correct IP address and directing you to this domain. Browsers use multiple servers to access different website information and remember it in the long run.

For example, you’re searching for our website, glimp. It’s much easier for your browser to input the domain name, ‘,’ instead of remembering the IP address numbers This makes it easier for your device to locate you at the right address.

How do DNS servers resolve DNS queries?

Each time you search for a domain name on your browser, DNS servers connect to several other servers and solve queries in four different steps. 

  1. The DNS resolver, also known as the DNS recursor, receives your request to show the IP address by entering a domain name.
  2. The root server then returns the result of this request and lets the DNS resolver match the address of the Top-Level Domain (TLD) server where all the info is stored.
  3. The TLD server is queried through the DNS resolver, then returns to the Authoritative Name Server.
  4. Coming from the name itself, the Authoritative Name Server learns and redirects you to the IP address you’re trying to deliver.

Once the IP address is redirected to the right domain name, it will then be shown on your browser. This seems like a lot of work, but this actually happens within a fraction of a second.

Does changing your DNS server increase internet speed?

DNS servers are assigned automatically by your internet service provider. While this is convenient, this may also prevent you from taking advantage of the servers without heavy traffic, especially during peak times. 

Think of the DNS servers as the routes to your destination. In this case, this is the IP address of the domain name you’ve entered. These servers can experience heavy traffic, so it’s more efficient to look for alternative routes that can take you to the IP address quicker. If you’re using the default servers that your ISP has set, you have no choice but be stuck in heavy traffic.

By changing your DNS servers, you can choose to take the faster route to the domain name you’ve requested. This can show the website you’re trying to access a millisecond to a few seconds faster. It doesn’t increase your internet speeds in a way that influences the Mbps of your broadband plan. It simply helps the user experience to feel snappier.
