DNS Client Overview
If your network devices require connectivity with devices in networks for which you do not control name
assignment, you can assign device names that uniquely identify your devices within the entire
internetwork using the domain name server (DNS). DNS uses a hierarchical scheme for establishing host
names for network nodes. This allows local control of the segments of the network through a
client-server scheme. The DNS system can locate a network device by translating the host name of the
device into its associated IP address.
