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.
