DNS forwarders are the DNS servers which forward DNS queries of clients to external DNS servers. For example if a DNS client sends a query to resolve the IP address of yahoo.com to a DNS server and if the DNS server is in the local area network it can forward the query to the DNS server of the ISP. Assuming that the DNS server of your ISP is 220.127.116.11 by following the steps given below you will be able to configure a local DNS server as a DNS forwarder to forward all the queries to external or in this case ISP’s DNS address.
- Log on to the DNS server using administrative privileges.
- Click on Start button.
- From the start menu go to Administrative Tools and from the submenu click on DNS.
- From the opened snap in right click on the computer name which is PCTIPS-3000 in this case and click on Properties.
- On Properties box go to Forwarders tab.
- On the Forwarders page in Selected domain’s forwarder IP address list text box type the DNS IP address of ISP for this example which is 18.104.22.168 and click on Add button.
- Click on Ok button to accept and confirm your configuration.
You can add multiple DNS forwarders IP addresses using this method.
