Complete Overview of DNS Cache

Many website owners around the world are quick to buy the best domain name for their websites. However, they don’t know what is DNS cache is or its importance in website development. In the technological world we live in, it is pretty common to be aware of all the terminologies and keywords. Even though we know how to use basic computer devices, understanding all their actions and reactions is a different ball game.

Domain Name System (DNS) cache is temporary storage for info regarding all the previous look-ins of a machine’s operating system or internet browser. By checking a particular website continuously, your machine’s operating system has a local copy of it. As a result, when you open that website the next time, your operating system can retrieve it quickly. Therefore, the website’s URL can coincide with your system’s IP address effectively. The primary responsibility of all different types of caches is practically the same.

Importance of DNS Caching

Firstly, the clearance of caches is essential for guaranteeing efficient access to web pages. If the web page changed its location since its IP address was cached, the web browser might display the HTML 404 error. Even though the website has an online status, the cache gives the browser an inaccurate IP address. This prevents the user to interact with the active page.

Secondly, the clearance of caches is vital for improving network security. Most operating systems, such as Windows and almost all other internet devices, can create a cache. Although this ability is for the maintenance of DNS lookup efficiency, it shows that the operating system and the internet browser have a compilation of website activity whether they know about it or not. By deleting all of the previous DNS records, you will disable the malicious agents from abusing your personal information.

One of the biggest reasons to flush DNS cache is important is to improve your site page’s loading speed. When you open a website for the first time, it will display a small image of that website so that it is easier for the system to pull up when you revisit it. However, caches may also be the reason why your website has a low loading speed. Especially when you have published content or any high-quality image, the visitors may experience a low loading speed of that website. As a result, you may get a low Google pagespeed insight score.

The reason behind the low insight score is that the small image initially created by your machine’s operating system may create a conflict with the changes made to the website. As a result, you have to either look for a different browser or consider browsing in private mode. If you want to improve your website’s loading speed, make sure to clear your DNS cache.

How to Check our DNS?

If you want to be checking your DNS cache, you simply need to go through the set of instructions that your operating system has in store. Every operating system has a sequence of instructions to view the contents of a specified cache. This process is pretty routine for mainstream developers around the world. Depending on the operating system you use and the website platforms that you have visited, you can view the DNS contents by going through the following instructions:

1. Windows

For checking your DNS cache on Windows, you simply need to go to the command prompt, where you will type the command “ipconfig /displaydns.”. After clicking on “Enter”, you will be able to see all of the DNS records.

2. Mac

Purpose of DNS Caching

The internet always relies on the registered domain names to maintain an index of all the websites alongside their corresponding IP addresses. Basically, the internet considers the registered domain names like a phonebook. It takes into account all of the necessary details of a website.

With a phonebook, you don’t need to remember every person’s phone number. It is the only thing with which mobile phones interact with each other. Similarly, checking your DNS cache will help you avoid memorizing all of the website’s IP addresses, which is the only way operating systems interact with websites.

To speed up a slow website, you must understand what is DNS cache. When you ask your browser to load a particular website ( Your web browser will ask your router to provide the IP address. The DNS server has already stored the DNS server address. Therefore, it tells the DNS server to provide the IP address of the hostname. The DNS server will be able to fetch the required IP address of, which will make it understand the website you are asking for. This will allow the browser to load the required web page.

This cycle repeats for every website that you visit. Every time you open a website of a particular hostname, the web browser will send a request to the internet. However, the request will not be guaranteed completion unless the site’s name is fully converted into an IP address.
