Everything about your proposal looks fine, except that the version of
BIND 8 that you are proposing to use is old and has known vulnerabili-
ties.  Please go to the ISC BIND Web and get a copy of the current
stable BIND 9 release (which should be 9.2.0 by the time you get this,
I hope), or of BIND 8 if you would really prefer that.

Remember to read the document specifying some of the differences
between BIND 4 and BIND 8, and BIND 8 and BIND 9.  There are some
differences that should be minor, unless you have been using some
illegal constructs that are now being enforced against.
