First, my thanks to Glen A. Herrmannsfeldt <gah@cco.caltech.edu>, who
gave me this wonderfully simple answer:
The trick to this is to configure my nameserver as the primary for the
domain econ.yale.edu, but as the secondary for the
32.132.130.IN-ADDR.ARPA domain, and it will then go to a primary
nameserver only when there is a 130.132.32.* reverse lookup whose
address isn't in its tables. Why I didn't think of trying this myself
is left as an exercise for the reader. ;->
