To set up your server as a DNS Server, it’s essential to configure both DNS Forward and Reverse Lookup Zones. The Forward Lookup Zone resolves hostnames to IP addresses, while the Reverse Lookup Zone does the opposite.
Understanding Forward and Reverse Lookup Zones
A Forward Lookup Zone acts like a phone book, translating domain names into IP addresses. This zone uses A (Address) records to facilitate web browsing, enabling devices to find the servers that host websites.
In contrast, a Reverse Lookup Zone flips the process, converting IP addresses back into hostnames. It employs PTR (Pointer) records for identifying hostnames associated with specific IP addresses, which is useful for network management and device recognition.
Before creating these zones, it’s crucial to align with your organization’s naming conventions and IP standards.
Steps to Configure Forward Lookup Zone
- Open Server Manager and select Tools > DNS.
- Right-click on the server name and choose New Zone.
- Follow the wizard and choose Primary Zone, then click Next.
- Select the Forward Lookup Zone option and proceed.
- Enter a Zone name and proceed to the next step.
- Choose Create a new file with this file name and provide a filename with a “.dns” extension.
- Decide on the dynamic updates option and click Next.
- Review the summary and click Finish.
You can verify the new zone by expanding Forward Lookup Zones.
Steps to Configure Reverse Lookup Zone
- In the Server Manager, access the DNS wizard.
- Right-click on the server name and select New Zone.
- Click Next to continue through the wizard.
- If necessary, select Primary zone and click Next.
- Choose the Reverse lookup zone and click Next.
- Specify either IPv4 or IPv6 Reverse Lookup Zone.
- Fill in either the Network ID or the Reverse lookup zone name and click Next.
- Provide the zone name and proceed.
- Set the dynamic update schedule and click Next.
- Complete the setup.
Check the newly created zone under the Reverse Lookup Zones directory.
Additional Tips
If you need to perform a reverse DNS lookup on Windows, you can use the nslookup command in the Command Prompt by typing nslookup <ip-address>, replacing <ip-address> with the desired IP.
