A name server also known as the Domain Name System (DNS) that helps to connect a domain to a web server or mail server on the Internet.
A name server translates domain names into IP addresses. This makes it possible for a user to access a website by typing in the domain name instead of the website's actual IP address. The name server in your domain records points to your web hosting to ensure that DNS functions correctly, and your website can be accessible via your domain.
