Explanation:
A forwarder is a Domain Name System (DNS) server on a network that forwards DNS queries for
external DNS names to DNS servers outside that network. You can also forward queries according to
specific domain names using conditional forwarders.
You designate a DNS server on a network as a forwarder by configuring the other DNS servers in the
network to forward the queries that they cannot resolve locally to that DNS server. By using a
forwarder, you can manage name resolution for names outside your network, such as names on the
Internet, and improve the efficiency of name resolution for the computers in your network.
