The DNS (Domain Name Service) client provides the ability to resolve IP addresses to hostnames and vice versa, and is always enabled on the appliance. 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 in Oracle ZFS Storage Appliance Customer Service Manual logs to indicate the location from which a user performed an auditable action and in Analytics in Oracle ZFS Storage Appliance Analytics Guide to provide statistics on a per-client basis.
The configurable properties for the DNS client include a base domain name and a list of servers, specified by IP address. You must supply a domain name and at least one server address; the server must be capable of returning an NS (NameServer) record for the domain you specify, although it need not itself be authoritative for that domain.
