|
Host name resolution is the process that a
computer system uses to associate a host name with an IP address.
In order to use host names to
communicate with other IP devices, network devices such as routers
must be able to associate the host names with IP addresses. A list of
host names and their associated IP addresses is called a host table.
A host table might include all devices in a network organization. Each unique IP address can have a host name associated with it. The Cisco IOS software maintains a cache of host name-to-address mappings for use by EXEC commands. This cache speeds up the process of converting names to addresses. Host names, unlike DNS names, are
significant only on the router on which they are configured. The host
table will allow the network administrator to type either the host
name such as Auckland or the IP address to Telnet to a remote host.
