    DAC is the Dedicated Administrative Connection...If you enabled in on your server (it's optional and off by default), when you have a runaway process you can still connect, and maybe kill those processes ro undo other things that may have locked everyone out, like a poorly written logon trigger.

    you can read plenty about it on BOL;

    it doesn't have a specific or different port than your server. it's a connection option for when you connect, say via SSMS or via SQLCMD
