DNS Configuration

The DNS (Domain Name Service) client provides the ability to resolve IP addresses to hostnames and vice versa, and can be enabled or disabled. Optionally, secondary hostname resolution via NIS and/or LDAP, if configured and enabled, may be requested for hostnames and addresses that cannot be resolved using DNS. Hostname resolution is used throughout the appliance user interfaces, including in Logs to indicate the location from which a user performed an auditable action and in Analytics to provide statistics on a per-client basis.

To configure and manage DNS, use these procedures:

• Configuring DNS - BUI, CLI

• Using the DNS Health Tool - BUI, CLI

• Testing Hostname Resolution (CLI)

• Adding a DNS Server - BUI, CLI

• Viewing DNS Server Status - BUI, CLI

To understand DNS usage for the appliance, use these topics:

• DNS Properties and Logs

• Active Directory and DNS

• Non-DNS Resolution
