Um, Mark, forward records too.

And I have to say the idea of delegating rDNS for 50 million consumers to 
50 million consumer something or others is simultaneously pretty amusing 
and pretty horrifying.

My cable company assigns me a different prefix every time the modem 
reboots, about once a month, and I think that's pretty typical.

R's,
