You just know.
It's like a door that says "Authorized entry only." If no one ever told
you that you're authorized, you can usually assume that you're not.

Unfortunately, BIND allows them by default.
We host DNS for thousands of customers, and we allow them to run slave
servers on their LANs, so we need to allow zone transfers. A customer is
authorized to transfer their own domains; everyone else is unauthorized,
but we don't enforce this (we would have to contact all the customers and
find out if they're running their own slaves so that we could set up access
