Can I use two different DNS servers?
At a minimum, you’ll need two DNS servers for each Internet domain you have. You can have more than two for a domain but usually three is tops unless you have multiple server farms where you would want to distribute the DNS lookup load. It’s a good idea to have at least one of your DNS servers at a separate location.
What is DNS zone example?
A DNS zone is a portion of the DNS namespace that is managed by a specific organization or administrator. A DNS zone is an administrative space which allows for more granular control of DNS components, such as authoritative nameservers. The domain name space is a hierarchical tree, with the DNS root domain at the top.
What is a private DNS zone?

How do I know if my DNS is primary or secondary?

What does changing your DNS to 8.8 8.8 do?
8.8 (and 8.8. 4.4) is Google’s public use DNS server. What the DNS does is essentially translate what you type into the address bar into something the computer can understand (and vice versa). If you type example.com into the address bar, for example, your DNS translates it to 93.184.

Changing your current DNS settings to the OpenDNS servers is a safe, reversible, and beneficial configuration adjustment that will not harm your computer or your network. … You can print out this page and write down your previous DNS settings if desired.
Why do I have 2 DNS servers?
The theory of having more than one is simply that if the Primary DNS is off line, your system can query the secondary DNS server. Primary and secondary (and other) DNS servers are supposed to be on separate networks, if one link is down, the second link will be up. There are a number of problems with this in practice.
Should private DNS be off?
