DNS stands for Domain Name Service, and it’s at the heart of the internet. DNS makes it such that you don’t have to type an IP address to get where you want to go. Without DNS, instead of just typing, say, “Google” into your browser, you’d have to remember an address like 142.251.16.100. In other words, DNS makes the internet user-friendly. Your desktop, laptop, tablet, and even phone require DNS to function properly.
