DNS deployment roles - BlueCat Integrity - 9.5.0

Deployment roles determine the services provided by a server. A deployment role creates a client-facing service, specified with an IP address, on a network or published server interface. Each server interface can have multiple DNS roles and one DHCP role. When multiple roles are assigned, the most locally-specified server role takes precedence. For example, if deployment roles are set at both the DNS view and DNS zone level, the role set at the zone level applies to the DNS zone. Roles set to None aren't deployed.

When assigning deployment roles, you select a server and server interface for the role. Only servers that support the deployment role are available to be selected, so you can't assign a deployment role to a server that doesn't support the role. For example, you can't add DHCP deployment roles to a DNS Caching server.
