Understanding Forwarders
A forwarder is a Domain Name System (DNS) server ona 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.
The following figure illustrates how external name queries are directed with forwarders.

Conditional forwarders
A conditional forwarderis a DNS server on a network that forwards DNS queries according to the DNS
domain name in the query. For example, you can configure a DNS server to forward all the queries that it
receives for names ending with corp.contoso.com to the IP address of a specific DNS server or to the IP
addresses of multiple DNS servers.
