Adding static host name to IP address mappings in a router (like a UNIX /etc/hosts file) can make life easier. These can override DNS entries for the host when needed, and can make easy references to other systems or devices that are not appropriate for DNS entries.

To add the mapping router1 to 172.31.1.1:

conf t
ip host router1 172.31.1.1
^Z
