I agree that's the way the Internet should work.  I disagree that DNS on
a cable modem is a reasonable solution.

Yes.

How much do you know about the Internet?  How much do you know about
DNS?  Enough to be dangerous?

I care.  My customers care.  They like knowing that in the unlikely
event their website goes down people won't be told it doesn't exist.

Lots of people do it that way.  Lots of people on this list do it this
way.  Some of them even think they're right in doing it this way.

I don't.
