What Is A DNS Server?

A DNS (Domain Name System) server is a protocol or system that takes domain names and converts them into IP addresses needed to access particular websites. A DNS server is essential for accessing websites on the internet, as it acts as a sort of phone book for the internet. 

In order to access website information, browsers communicate with origin servers or CDN edge servers. DNS is a complicated system as it does not store information in a single database but instead is distributed among many servers throughout the world. You don’t have to consider any of those low-level details if you’re an internet user.  

Whenever you go online, your ISP automatically connects you to a DNS server, which will find the IP address for any URL you enter into your browser.
