Domain name: abc.com Name Server: ns1.abc.com and ns2.abc.com
I am running a DNS server and hosting the zone (abc.com) on-premise.
When a client wants to resolve *.abc.com, it will query ns1.abc.com or ns2.abc.com, that is straight forward.
The question is how does it resolve ns1.abc.com before it can sends query to it?
