Configure Views

Views allow you to present one name server configuration to one set of hosts and a

different configuration to another set. Whether you choose to use views depends on

your overall architecture, firewall configuration, and security policy.

You only need to configure and maintain a single

named demon process instead of

running multiple

named processes on the same host (restricting each to a different

network interface) or establishing completely separate name server host machines,

each serving a different community of hosts. When you set up views, there is a single

interface box (sitting inside on the internal network or outside on the perimeter

network) that distinguishes inside from outside by IP address. With two boxes, one

inside and one outside, the firewall must distinguish inside from outside.

In the following example, two views are available in the server, one for internal clients

using addresses

10.53.0.2 and 10.53.0.3 and the other for external clients that

can be any address.

For the internal clients, the local zone file is root.hint. For the zone

example, the local

zone file is internal.db.

For the external clients, the local zone file is root.hint. For the zone

example, it is

example.db.
