How to Configure Reverse Lookup Zone
Configure Reverse Lookup zone
We have configured Forward lookup zone. Now we need to create a Reverse lookup zone before we use it.
Do Right click on Reverse Lookup Zones
On welcome screen click on Next
Select the primary zone.
We need not store zone in ADS so Remove the check mark from Store the zone in Active Directory
We need not store zone in ADS so Remove the check mark from Store the zone in Active Directory
Give the network ID from the IP address of the server. Our server IP is 192.168.0.1 so I will set here 192.168.0 [ network partition of IP]
Keep the default name for zone file and click on next
Select Allow both nonsecure and secure dynamic updates. Don't use this option in public network.
On the summary table just click on finish
We have created both zone file for DNS server. Now we need to tell DNS server about our pointer for DNS server.
Expand Reverse Lookup Zones and select 192.168.0.x Subnet [ if you have used different IP for the server then here you will find your IP address's subnet ].
Right click on it and select New pointer
Now give the host ID from IP address. We will give 1 as we are using 192.168.0.1 IP address.
At this point, we have configured both forward and reverse lookup zone. But all these effects will take place after restarting of DNS. DNS service can be restart in two ways either by restarting the service or do a complete restart of the server.
To restart the DNS service Right click on Server and select restart from all task
The configuration of the DNS server can be verified by launching nslookup. To launch nslookup right-click on Server and select nslookup
If you see the default server name in output mean DNS server has been properly configured and functioning. But we haven’t restarted the server so you will not see the server name here.
To apply all these changes Restart the server, After Restart verify it again and you will see the default server name in nslookup
Additional testing of DNS can be done by pinging it by name. Go on any client computer and ping the DNS server. [ Before doing this set preferred DNS IP to 192.168.0.1 other client.]
