If you find yourself often connecting to the same devices and are looking a quicker way to telnet to them rather than constantly typing the entire IP address for each one. Or if you have a very large network and find it hard to remember every devices IP address, but you can remember the host name of the router, then the ‘ip host’ command is a saving grace.
Once defined you can now connect to each device on your network via telnet by just using the host name you have defined and linked to an IP address.
Below is a live demo showing the configuration of three routers with the ‘ip host’ command.
