Some DNS servers respond to port 53, but they're not supposed to do that to DNS queries.

I would bloody well hope they all do.

New Sorry, I mis-typed.
I meant some DNS servers make a response back to port 53, rather than back to the port the connection came in on. English vagaries aside, I'm probably mis-remembering something the O'Reilly book. :-)

Is it enough to love
Is it enough to breathe
Somebody rip my heart out
And leave me here to bleed
 
Is it enough to die
Somebody save my life
I'd rather be Anything but Ordinary
Please
