This is a very annoying feature on a Cisco switch…
Router>en\ Translating "en\"...domain server (255.255.255.255)
But, this is how to turn this behavior off. Run this command in privileged exec mode.
arya(config)#no ip domain-lookup
And this behavior will no longer occur.
arya#help2 Translating "help2" % Unknown command or computer name, or unable to find computer address
This will be a great saviour of your sanity when you do a typo, this will not happen. But if it does, just press Ctrl-Shift-6.
