Whenever you move around the internet, accessing different websites, you leave a digital footprint.
The captured data is then used to understand the customer’s website experience and optimize the website without actively disclosing personal details.
While most users rely on history and cookie clearing to protect their privacy or put an end to data collection, very few are actually aware that their own operation systems capture their browsing behaviors.
A good example is the DNS cache, which stores the IP addresses for every website you visit. This allows your browser to find this information quickly, thus allowing faster connections.
However, there are reasons why you may need to flush your DNS cache regularly. In this article, we will look at the reasons as well as how to flush your DNS cache.
But before we dive into the details, let’s get an overview of what DNS cache is.
What is DNS cache and how does it work?
The Domain Name Server (DNS) cache, sometimes referred to as DNS resolver cache is a database that’s temporarily maintained by your computer’s operating system.
The database stores all records of the recently visited websites, including their IP addresses and other internet domains.
Simply stated, the DNS cache is like your computer’s phonebook. With a phonebook, you do not need to remember everyone’s contact information.
DNS works in a similar way, in that it stores DNS information of every website’s IP address you visit or attempt to visit.
The DNS information stored allows your browser to find the website quickly. What this means is that, once you enter the domain name of the website you are looking for, your browser will first look for the DNS information in the DNS cache. This information will then be used to visit the website.
However, if the DNS information is missing in the local DNS cache, your browser will be prompted to collect it from other DNS servers.
The principle behind DNS technology is to ensure that your browser takes the shortest route when locating any website on the internet.
Why is it important to flush your DNS cache?
There are a number of reasons why you may be prompted to flush your DNS cache. Here are some of the reasons.
- Speed up DNS propagation: But what is DNS propagation, you might ask? This is the time frame required by DNS servers across the globe to update cached information for a domain name after making any changes to your domain or when you are moving your site to a new host. It is determined by the changed Time to Live (TTL) value of DNS records. Sometimes the DNS information can take as much as 72 hours to update completely. As such, you will most likely get
