authoritative dns server is server that has own databases that has name resolution for the clients that for resolve from name to ip address and for ip address to name. non-authorititative dns server is server that forward request of dns client to authoritative dns server for resolve.
Unbound - DNS Server - was created in 2007.
Often it is the server that is hosting the DHCP, so it can not assign its own address. But usually its just useful if the servers always have the same IP address. For example if a server is hosting a DNS server (as company servers often do), and all the workstations in the company are looking to that IP address for DNS info, the IP addrss can not change. If the IP address of the DNS server were to change then no computers on the network would be able to resolve domain names.
The primary DNS server is usually the same as the router's IP adress.
If a DNS server cannot find the answer to the DNS Query in its own database it will first query the forwarders (if there are any configured) and then ask the root server. root servers (by default) are the master DNS servers of the Internet.
The prefered DNS server for the site is the server which sends the dns zone updates to all the other servers in the site. The primary DNS zone is created on the server and it has the authority to send changes in zone to other servers
