Have you ever typed a command into the Cisco console incorrectly and left waiting for a minute or two as the router tried to “translate” your command to a domain server of “255.255.255.255”? The router is set by default to resolve any word that is not a command to a Domain Name System (DNS) serfver at address “255.255.255.255”. If you are not going to set up DNS, turn off this feature to save you time, stress and swear words.
1. Log into router
no ip domain lookup
copy running-config startup-config
