I would agree with this - a more standard approach is to have all internal clients point to your internal DNS server then have that server set up with a forwarder to your external DNS - that way internet DNS requests are sent to your DNS server which then performs the query on your client’s behalf.
This scenario has many advantages a big one is your internal DNS server will cache the queries for internet sites – speeding up name resolution and meaning you clients don’t have to leave the building for name resolution
