Serving two subnets on same VLAN

The approach that I took years ago for this problem was to enclose the subnet declarations inside a network declaration.  I then used a class identifier to determine which DHCP IP address range to use for the device.  I also had to use pool declarations so that I could have access controls to restrict address allocations to members of a class.
