To add an additional DNS server, go to the 'Internet safety' page in the web interface of your router and click 'Add a DNS server' in the 'DNS servers' section.
In the 'DNS server address' field, enter the IP address of the DNS server (in our example it is a public DNS server from Google 18.104.22.168) and then click 'Save'.
The DNS servers added here will be used by home devices which don't have any Internet safety service applied.

NOTE: Important! The logic of DNS in Keenetic routers is that requests are sent to all available DNS servers, both received from the ISP and entered manually. And the reply that comes more quickly is used for name resolution.
TIP: Tip: Sometimes, you need to know through which DNS server your requests are processed. This can be done using online services, for example, whatsmydnsserver.com or dnsleaktest.com.
