You can use the following procedure to add a host address (A) resource record to a zone. Pointer (PTR) resource records that are created automatically when you add an A resource record to a zone are deleted automatically if the corresponding A resource record is deleted.

You can perform this procedure by using the DNS snap-in or by using the Dnscmd command-line tool.

Administrative credentials

To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using the Run as command to perform this procedure.

Adding an A resource record to a zone

  • Using the Windows interface

  • Using the command line

To add an A resource record to a zone using the Windows interface

  1. Open the DNS snap-in.

  2. In the console tree, right-click the applicable forward lookup zone, and then click New Host (A).

  3. In Name, type the Domain Name System (DNS) computer name for the new host.

  4. In IP address, type the Internet Protocol (IP) address for the new host.

  5. As an option, select the Create associated pointer (PTR) record check box to create an additional PTR resource record in a reverse zone for this host, based on the information that you enter in Name and IP address.

  6. Click Add Host to add the new host (A) resource record to the zone.

Note

To open the DNS snap-in, click Start, point to Administrative Tools, and then click DNS.
