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
upgrade.
From https://www.isc.org/software/dhcp/history
"... 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.
