What is DNS?

DNS stands for Domain Name System. It is essentially the phonebook of the internet. When you enter a website’s URL into a browser, the DNS server translates the domain name into an IP address, allowing your computer to connect to the website’s server and display the web page.

Every device connected to the internet has a default DNS server assigned by the ISP. However, you can manually change the DNS server you use for better performance or more features.
