Usually your internal DNS server should cache the RRs, and keep
in mind that clients query forwarders of the ISP usually.
Alternatively you can allow your internal DNS-server to do
recursive queries be itself, but then you have to allow the whole
net to send packets to the domain port of your internal server,
so I would prefer to forward all queries to an ISP DNS server.
