Configuring the Domain Name Service (DNS)

DNS forwarders

DNS forwarders enable systems with limited network access to pass DNS requests to the rest of the network. For example, your network may contain a computer that serves as a centralized mail hub and gateway to other networks or the Internet. In this instance, direct access from other computers to the outside is restricted in that it must flow through the gateway. You can configure DNS to operate in the same way by designating the gateway machine (which must be a DNS server) as a forwarder.

If your system is a primary, secondary, or caching-only DNS server, you can use forwarders. Add, modify, or delete forwarders by editing /etc/named.conf. Forwarders are stored as IP addresses.
