Recipe 13.2 Creating a Reverse Lookup Zone

13.2.1 Problem

You want to create a reverse lookup zone. A reverse lookup zone maps IP addresses to names.

13.2.2 Solution

13.2.2.1 Using a graphical user interface

1. Open the DNS Management snap-in.

2. If an entry for the DNS server you want to connect to does not exist, right-click on DNS in the left pane and select Connect to DNS Server. Select This computer or The following computer, enter the server you want to connect to (if applicable), and click OK.

3. Expand the server in the left pane and click on Reverse Lookup Zones.

4. Right-click on Reverse Lookup Zones and select New Zone.

5. Click Next.

6. Select the zone type and click Next.

7. If you selected to store the zone data in Active Directory, next you will be asked which servers you want to replicate the DNS data to. Click Next after you make your selection. (This only applies for Windows Server 2003).

8. Type the Network ID for the reverse zone or enter a reverse zone name to use.

9. Fill out the information for the remaining screens. They will vary depending on if you are creating a primary, secondary, or stub zone.

13.2.2.2 Using a command-line interface

The following command creates an AD-integrated reverse zone:

> dnscmd <DNSServerName> /zoneadd <ZoneName> /DsPrimary

13.2.2.3 Using VBScript

' This code creates an AD-integrated reverse zone. ' ------ SCRIPT CONFIGURATION ------ strServer  = "<DNSServerName>"  ' e.g. dc1.rallencorp.com strNewZone = "<ZoneName>"       ' e.g. 8.10.192.in-addr.arpa. ' ------ END CONFIGURATION --------- set objDNS = GetObject("winMgmts:\\" & strServer & "\root\MicrosoftDNS") set objDNSZone = objDNS.Get("MicrosoftDNS_Zone") strNull = objDNSZone.CreateZone(strNewZone, 0 , True) WScript.Echo "Created zone " & strNewZone

13.2.3 Discussion

Creating a reverse zone is very similar to creating a forward zone. See Recipe 13.1 for more information.
