I know the semantics don’t sound right, but I just came up with this question.
Let’s say a client queries a DNS server for
www.example.com, which recursively asks the root server, then the TLD, then
example.com until the IP is found. Then this DNS server would store the IP in its cache.
Since I’ve read that:
“…an authoritative nameserver is one that satisfies queries from its own data without needing to reference another source…”
Would this cached information make the DNS server authoritative for
www.example.com? I know the answer is probably “no” but I can’t figure out the exact reason.
I’ve also read that a server can serve authoritative data for a zone which is not delegated to them, which is what arose my question.
