Device Configuration : Configure : Network : DNS
DNS
Use DNS page to configure the DNS settings of the Device
DNS server is configured at the time of installation. You can add additional DNS servers to which device can connect for name resolution. If multiple DNS are defined, they are queried in the order as they are entered.
* You can also view and manage the DNS server status on the Monitor and Analyze > Diagnostics > Services page.
When you want external domains names to be resolved through internal DNS Servers in your network, you can add routes to such Servers. This will decrease the Internet traffic over the network and speed up DNS Client requests as queries will not be forwarded outside the network. Also, DNS information would be less exposed on the Internet thus enhancing security.
