About the DNS service

The Domain Name Service is a service that translates domain names into IP addresses. The network layer of the Internet uses IP addresses to identify domains; however, Internet users prefer to use names rather than IP addresses because they are easier to remember. Every time you use a domain name, the DNS service translates the domain name into its corresponding IP address. For example, when you type the domain name example.com in the Address field of your browser, the DNS service translates the name into its IP address 1.2.3.4.

The DNS service enables client computers on your network to register and resolve domain names.

The DNS service comprises the key component - Microsoft DNS

# Microsoft DNS

Microsoft DNS is Microsoft's implementation of the DNS protocols. When you provision the Microsoft DNS component for a site, all the DNS entries necessary for the site are created automatically. In addition, the site administrator can create zones and records in DNS. The number of zones and records that can be created depends on the resources sold to the site.
