I saw the message from Thomas and am happy to report that ISC DHCP 2.0.3 does indeed support shared networks.
I have been considering upgrading to a more current version, just need to figure out how to do this without breaking anything.

As Paine, Thomas Asa wrote yesterday, this is a
shared network and you simply declare it as such
and it will work automagically.
However, version 2 is ancient - really ancient
and has been unsupported for many years. From my
very vague memory of it, it doesn't support
shared networks. You really should consider an
"... Release 3.0, which had its alpha release in
March 1999 and its final release in January 2003."
Even 3.0 went end of life over a year ago.
