The digital landscape is a dynamic ecosystem driven by a plethora of processes and systems. Central to the seamlessness of internet navigation is the Domain Name System (DNS). While the term DNS is frequently encountered by anyone working in IT or studying digital systems, there’s an intricate component of this system that’s indispensable: the DNS cache. This post offers an in-depth exploration into the concept of Domain Name System cache, its functionality, and its significance.

What is DNS cache?

DNS cache is, in essence, a temporary storage (typically in a device’s RAM) that maintains records of recent visits and attempted visits to websites. This storage or ‘cache’ comprises the domain names and the IP addresses associated with them. It is the bridge between the domain names humans find intuitive and the IP addresses machines utilize.

What objective does Anycast DNS serve?

A communication or routing technique called Anycast DNS makes it possible to send and receive data more quickly. Using this technique, a single IP address can be typed into several DNS servers worldwide. Any of them is capable of responding to the request. The intended outcome is for the server to react physically closest to the user. This greatly accelerates the response time (DNS resolution).

The DNS resolution process is the core of understanding how the Domain Name System works. That’s why, in this article today, we will explore it. So, let’s start. 

DNS resolution description

Domain Name System (DNS) resolution is the procedure of acquiring an IP address (IPv4 or IPv6 addresses) through its domain. This is done to make life easier for online users. The easiest way to understand DNS resolution is to picture a phone book with the names of people in it. But because it’s so hard to remember their phone numbers, we don’t. The same idea applies to DNS resolution. It gets to its IP address via the domain name by sending DNS queries.
