Resolution Of Host Names; Enabling Dynamic Resolution Of Host Names - Dell Z9000 Configuration Manual

Resolution of Host Names

Domain name service (DNS) maps host names to IP addresses. This feature simplifies such commands as
Telnet and FTP by allowing you to enter a name instead of an IP address.
Dynamic resolution of host names is disabled by default. Unless you enable the feature, the system
resolves only host names entered into the host table with the ip host command.
The following sections describe DNS and the resolution of host names.
