DNS stands for “Domain Name System”. 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.
This section contains essential information about making DNS changes to your web site. Please read this document thoroughly. Topics include an important message for beginners, a short DNS tutorial, an explanation (with examples) of: A, CNAME, NS, and MX records, and how to change DNS settings.
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.
