Setting the DNS server address prior to joining the domain is essential for two reasons. First, the DNS server will be used to resolve hostnames (names of computers and other devices) into IP addresses. If the DNS server is not registered with the domain name system (DNS), then it will not be able to resolve domain names.

Second, the DNS server must be registered with the domain name system in order to provide domain name resolution. If the DNS server is not registered with the domain name system, then it will not be able to resolve hostnames into IP addresses.

In order to register the DNS server with the domain name system, the user must have administrative access to the DNS server. If the DNS server is not registered with the domain name system, then the user will not be able to access the DNS server and will not be able to resolve domain names.
