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.
You must have the DNS service installed to provision DNS records to organizations for the following services:
Hosted Exchange 2003
Windows Web Hosting
The DNS service comprises the key components - Microsoft DNS and DNS logs. You can use these components in combination or independently, depending on your requirements.
Microsoft DNS is Microsoft's implementation of the DNS protocols. When you provision the Microsoft DNS component for an organization a site, all the DNS entries necessary for the organization site are created automatically. In addition, the organization 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 organization site.
DNS logs maintains a record of the DNS events such as addition or deletion of records or zones. It enables you to upload custom scripts that can be executed when certain DNS events occur.
