Yes, it's a built-in function of bind-9 called views.

You better upgrade to a more recent version, bind 9.2.1 will build
nice on freebsd ( there is no known security hazards with 9.1.3, but
there is a number of enhancements and fixes)

Together with the source is an excellent documentation "the arm book"
which has some nice examples of using views.

Mail me if you need more detailed info.
