= Authoritative Nameserver =
An authoritative Nameserver is a nameserver (DNS Server) that holds the actual DNS records (A, CNAME, PTR, etc) for a particular domain/ address.
A recursive resolver would be a DNS server that queries an authoritative nameserver to resolve a domain/ address.
If I have a DNS server in my network that holds an A record for foobar.com, my DNS server would be authoritative for the foobar.com domain.
If clients needed to access foobar.com, they could query my DNS server and they would get an authoritative response.
