A secondary DNS server is a DNS server that is used to supplement or backup the primary DNS server. When the primary DNS server is not operational, or when there is a network issue that prevents it from providing correct DNS service, the secondary DNS server can be used to provide some of the necessary DNS service.

A secondary DNS server can also be used to provide additional DNS services, such as DNS load balancing or DNS security. When using a secondary DNS server, it is important to make sure that the settings on the primary DNS server are configured correctly.

Otherwise, the secondary DNS server may not be able to provide the necessary DNS service.

When using a secondary DNS server, it is also important to keep track of the DNS settings for both the primary and secondary DNS servers. If the settings on either server change, it is important to update the settings on both servers.

Otherwise, the DNS service may not be working correctly.

A secondary DNS server can be a useful tool for providing DNS service when the primary DNS server is not operational.
