It’s a system that lets you connect to websites by matching human-readable domain names (like wpbeginner.com) with the unique ID of the server where a website is stored. Think of the DNS system as the internet’s phonebook. It lists domain names with their corresponding identifiers called IP addresses, instead of listing people’s names with their phone numbers. When a user enters a domain name like wpbeginner.com on their device, it looks up the IP address and connects them to the physical location where that website is stored. How Does DNS Work? The internet is a giant network of computers. Each device connected to the internet is assigned a unique IP address which helps other computers identify it. This IP address is a string of numbers with periods that looks like this: 192.124.
