Creating Resource Records using DNSCMD

by Mitch Tulloch [Published on 29 Oct. 2009 / Last Updated on 3 May 2009]

How to use the DNSCMD command to create a resource record from the command-line.

If your DNS server is running Windows Server Core, you can create resource records from the command-line by using the DNSCMD command. For example, to create a host (A) record in the fabrikam.com on authoritative DNS server SEA-SC1 for a server named SEA-SRV8 that has IP address 172.16.11.75, do the following:

dnscmd SEA-SC1 /recordadd fabrikam.com SEA-SRV8.fabrikam.com. /aging /openacl A 172.16.11.75

Verify the result by listing all A records in the domain as follows:

dnscmd SEA-SC1 /enumrecords fabrikam.com fabrikam.com. /type A

Returned records:

@ [Aging:3571189] 600 A 172.16.11.30

SEA-DESK155 [Aging:3571191] 1200 A      172.16.11.80

sea-sc1 [Aging:3571238] 3600 A  172.16.11.30

SEA-SC4 [Aging:3571189] 1200 A  172.16.11.33

SEA-SRV4 [Aging:3571192] 1200 A 172.16.11.81

SEA-SRV8 [Aging:3571246] 3600 A 172.16.11.75

The /aging switch in the previous command indicates that the new resource record can be aged and scavenged. If you omit this parameter, the
resource record remains in the DNS database until it is updated or removed manually. The /openacl switch indicates that any user can modify this
record. Without this parameter, only administrators can modify the record.
