Nothing at all, except that it stops this behaviour:

More specifically, IOS command mode will assume by default that any non 
recognised command is actually a hostname which it should try to connect to 
- a fossilised relic of times past, when routers were often terminal 
servers.  You can stop it doing this by using "transport preferred none" on 
the appropriate line configuration.
