Domain Name System (DNS) - what is it?

What is DNS and why do we need it?

While your website may have a domain name such as "", it is actually hosted on an IP address which is a series of numbers serving as an identifier for your website. Every device on the World Wide Web has a unique IP address, and it is this IP address that your computer connects to when visiting a website. However, it is inconvenient for us to remember a string of numbers, so instead, the Domain Name Servers (DNS) help to translate the domain names into the relevant IP addresses. The DNS acts like a phonebook, storing both domain names and their respective IP addresses. This checking and translating is done automatically and usually very quickly. 

Example: your website may be called but it has a corresponding IP address of which is the numerical identifier used by networks and servers to find your website.
