The DNS servers are used to resolve hostnames to IP addresses on the DHCP clients.

The following steps are used to define the DHCP servers.

1. Click on DNS under Network in the Web GUI.

2. On the Network settings: DNS  page, you can define three different DNS servers with DNS 1 being the DNS server with the highest priority and DNS 3 being the server with the lowest priority.

5. Once the DNS servers are entered, click on Save to apply your changes.
