We have a network with the following info:-

Server IP 172.24.53.2
Subnet 255.255.255.128
Gateway 172.24.53.1

All the clients have static IP addresses but we want to change them to they
can obtain an IP address from the server. What is the maximum range I could
specify to setup a scope? I cannot change the subnet mask as the router is
under an Local authority contract (and they won't change this due to remote
access/other reasons).

Thanks.

The mask determines the Range
The Scope uses the *whole* Range
Use Exclusions in the Scope to tell what address that you do *not* want it
to give out.

If you have Static Addressing then you should have an IP List already. Find
a block of IP#s not in use. Adjust the Exclusions so that they disallow all
IP# but those. Take a group of Static machines "next" to the free addresses
(either above or below) and make them DHCP Clients.

Once they aquire an address, and hence "free up" the Static ones, you can
use the Exclusions to expand the number of addesses given out to include the
ones you just freed up. "Rinse & Repeat" until you have done all the ones
you want to do.

You should keep a range of IP#s at the "bottom end" for machines and devices
that are to remain static. Servers and Network Equipment should remain
Statically Addressed.

.....without the Net-ID and the Broadcast Address
