dns confusion, a couple of questions

Why?  There are name servers out there named washington, frodo,
titanic, horse, and "a".  Why the heck should they tell you what to
name your machine?

Now, I do have trouble understanding why people want to give their
machine the same name as their domain; but it seems to be all the rage
these days.

You may make either the canonical name, or something entirely
different.  The name server name may not, however, appear on the left
side of a CNAME (canonical name) record.  Nor may the domain name.

It found your reverse DNS OK.  It can't find the name "localhost" in
your domain.
