How to forward by DNS name within the local network?

Question

Domain Name System

Colleagues, tell me, you need to make it so that from the local network users entering www.NNN.com
are redirected to port 80 of the machine inside this local network

Answer 1

Create a static entry in the Mikrotik DNS on the IP of the local machine (the so-called Split-DNS)
IP -> DNS -> Static
PS
Or do it on any other DNS in the corp. network, if Mikrotik is not a DNS server for clients.
