If the server is handing out /24 network prefixes, then once your clients
bind the offered address in 10.0.0/24, they can no longer communicate with=
=20
the server in 10.0.1/24.
You can
a) give the DHCP server an alias IP address in 10.0.0/24 on the
appropriate interface
b) change the network prefix to 16 bits, so that 10.0.0 and 10.0.1
(and ALL other addresses with the prefix 10.0) are in the same=20
logical network space
c) renumber your DHCP pool
