How DNS Affects Your Internet Browsing Speed


For someone who does not have much technical knowledge of what goes on every time you connect to the internet, it is easy enough to overlook factors which affect your browsing speed. However, you only begin to appreciate the importance of a fast internet connection when you experience your network slowing down. One of the fundamental parts which affect how the internet operates is the domain name system.

What is a domain name system?

When you browse the internet, you begin by entering a hostname into the browser field. This hostname has a corresponding numerical format or IP address in the domain name system. What this domain name system does is to provide a user-friendly method of querying the internet instead of relying on the IP address of a particular website.

How does a domain name system work?

Every internet service provider carries a database of DNS names and IP addresses. When your initial query contains a DNS name which your internet provider can answer using their existing directory, your connection to the website is easier. By using the fastest speed directory, ensures quicker browsing.

What happens if your internet service provider cannot answer your DNS query? The provider will then check the cache. Your server’s cache contains information on all previous searches. If your internet provider can provide the answer to your query using cached information, the answer is non-authoritative which means you are getting your answer from a third-party.

If this method still does not supply the answer to your initial query, the next process is called recursion, which means your internet provider will use information from other servers to look for what you need. After obtaining this information, your internet provider will transfer it to your computer.

Considering the steps involved in answering every single internet query you make, DNS does impact the speed to which you receive an answer from your internet provider.

The effect of DNS on your internet speed

From the discussion above, you can see that DNS affects how fast your computer opens a specific website. While you cannot strictly say that DNS slows down internet speed, the process of establishing a connection can impact your browsing experience. To amend this, you can use an app that will speed up the directory request of your computer. You will get a set of recommended DNS servers from the app provider, and you need to update your router settings by doing the following:

  • Go to the router’s admin page
  • Select advanced settings
  • Take note of your current DNS server addresses
  • Replace current DNS server addresses with recommended addresses

After replacing your device’s DNS server addresses, you will experience faster connection and browsing speed. Before buying or downloading an application to speed up your internet connection, take time to research how the application functions. There are some factors which impact your internet speed and DNS is only one of them. You should first determine the real cause of the issue before finding the appropriate and effective solution.
