Add a machine record

Use the Server app to create a machine record. You must add records for each computer the DNS primary zone has responsibility for. Don’t add records for computers the zone doesn’t control.

A machine record or address (A) record is used to associate a domain name with an IP address. Therefore, there can be only one machine for each IP address because there can’t be duplicate IP addresses in a zone.

  1. In the DNS pane, click the Action pop-up menu gear, then choose Show All Records.

  2. Click Add add, then choose Add Machine Record from the pop-up menu.

  3. Click the Zone pop-up menu, then choose a zone.

    The machine record is added to this zone.

  4. In the Host Name field, enter the host name of the computer.

    This field is the basis for the A record of the computer. Reverse lookup pointer records are created for the computer.

  5. Click Add add, then enter the IP address of the computer.

  6. Enter comments about the computer in the text box.

    This field is the basis for the TXT record of the computer. You can store up to 255 ASCII characters in the text box. You can include the physical location of the computer (for example, Upstairs server closet B), the computer’s owner (for example, John’s Computer), or other information about the computer.

  7. Click Create.
