This concept is called "split DNS".

NSD does not have any ability to do split DNS. You have to run multiple
instances of it (whether on separate servers, or on separate instances
of one server).

BIND has this feature, and it's called "views". A single instance of
BIND can provide answers from different copies of a zone based on the
client's address.

Knot DNS has a limited variant of this feature, called "dnsproxy".
