Cisco domain lookup

Hello all, quick question if i may...

In this link: Prevent "Translating. domain server (255.255.255.255)" Messages after an Invalid Command is Entered on a Router - Cisco Systems

It talks about how a switch/router does a domain lookup when you type a command wrong in priv exec mode.

This line interests me "If no specific domain server has been configured on the router, the router will issue a broadcast for the command to be translated into an IP address".

What type of broadcast is that? I take it its not a Netbios lookup like on Windows but what would it be? I mean i know it would ARP if it knew the IP, but what if it just had the name of the host?

Thanks

The type of broadcast is a DNS broadcast. After looking at it's own local host table (the translating process) the router will send out a DNS broadcast in an attempt to find a DNS server to resolve the name to an IP address.
