DNS stands for Domain Name System, and it’s an essential component of the internet. The DNS is responsible for translating human-readable domain names, such as www.example.com, into the IP addresses that computers use to identify and communicate with each other over the internet.
In the context of WordPress, DNS is important because it determines where your website is hosted and how users can access it. When you register a domain name for your WordPress site, you’ll need to configure your domain’s DNS settings to point to the web server where your WordPress site is hosted. This allows users to access your site by entering your domain name into their web browser.
DNS also plays a role in managing email for your WordPress site, as you’ll need to set up MX records to specify the mail server that should handle email for your domain. Without properly configured DNS settings, your WordPress site and email may not function correctly.
