Jim,
If you followed Terrell's proposal, you would be
supernetting a class c address range. I have never
done that but it probably works fine. Personally, I
would select an address range in the private class a
or b ranges (10.x.x.x for class a and 172.16.0.0 -
172.31.255.255 for class b)The subnet mask for class a
would be 255.0.0.0 and the class b subnet mask would
be 255.255.0.0. You would have a lot of flexibility in
subnetting these later on if necessary. I don't think
you will have as much flexibility if you supernet a
class c but this is an area where I feel like I am
finally beginning to understand what is going on and
don't know all the ins and outs yet. If you move all
workstaions to dhcp, then you would just have to
readdress servers, network printers, switches (if you
use managed switches)and your router. A previous
poster warned about the dangers of having multiple
dhcp servers on a single lan. I couldn't agree more.
You invite all kinds of problems with multiple dhcp
servers. People that are doing it have been lucky if
they haven't run into significant issues. Hope this
helps
Dave

Hello Jim,

Why not just make one large /21 and adjust your DHCP
scope 
appropriately?  Say, 192.168.0.0/21.  This would give
you 192.168.0.1 
through 192.168.7.254, which is 2046 IP addresses. 
You could go a bit 
further and exclude, say, the first 255 addresses from
the scope 
(192.168.0.1 through 192.168.0.255).
