Can I use secondary DNS as primary?
DNS servers can be primary for one DNS zone and secondary for another DNS zone. Secondary DNS servers are not mandatory—the DNS system can work even if only a primary server is available. But it is standard, and often required by domain registrars, to have at least one secondary server.
What should my primary and secondary DNS BE?
Tap “Primary DNS” and enter in 208.67. 222.222, ensuring you are entering the “.” between each number, then tap “OK” to return to the DNS screen. Tap “Secondary DNS” and enter in 208.67. 220.220, then tap “OK” to return to the DNS screen.
How do I know if my secondary DNS is working?

What happens if the Primary DNS server goes down?
Provides redundancy in case the primary DNS server goes down. If there is no secondary server, when the primary fails, the website will become unavailable at its human-readable domain name (although it will still be accessible by its IP). Distributes the load between primary and secondary servers.
How can I tell which server is my Primary DNS server?
Examine the zone on the primary server (the server from which this server pulls zone transfers). You can determine which server is the primary server by examining the properties of the secondary zone in the DNS console. If the name is not correct on the primary server, go to step 4.
How to troubleshoot DNS server that failed recursive query?
