How do I...Install and configure a DNS server in Windows Server 2008?

Configure a Host (A) Record

A Host (A) record maps a host name to an IP address. These records help you easily identify another server in a forward lookup zone. Host records improve query performance in multiple-zone environments, and you can also create a Pointer (PTR) record at the same time. A PTR record resolves an IP address to a host name.

To create a Host record:
  1. Select DNS from the Administrative Tools folder to open the DNS console.
  2. Expand the Forward Lookup Zone and click on the folder representing your domain.
  3. From the Action menu, select New Host.
  4. Enter the Name and IP Address of the host you are creating (Figure O).
  5. Select the Create Associated Pointer (PTR) Record check box if you want to create the PTR record at the same time. Otherwise, you can create it later.
  6. Click the Add Host button.
