Increase Addresses

We currently have a scope of 192.168.1.x-192.168.2.254 with a mask of
255.255.254.0 .DHCP server is on .0 and our router is on .1 We want to
increase our address due to more devices being added to the network By adding
a .2 and .3 to the scope. I tried to delete the current scope and recreate it
192.168.1.x-192.168.3.254 with a mask of 255.255.254.0. . We were able to
obtain and IP from the .2 but could not ping or resolve and address on the
network. I reverted back to the original config for now. Any help would be
greatly welcomed

Check your subnet masks.

What should the mask be. I plan on removing the curretn scope and recreating
as 192.168.0.x-192.168.3.x What should the mask be

Network Subnet Mask #Hosts Host Range

510 Hosts
192.168.0.0 255.255.254.0 510 192.168.0.1 to 192.168.1.254

I would highly suggest using multiple Class C's and separate with a router.
Any more than 250 devices on a segment and performance blows.

Slight config error in original post we currently have
192.168.0.1-192.168.1.254 with a mask of 255.255.254.0 DHCP server is
192.168.0.100. We have a router configured with 192.168.1.254 and also our
default gateway. Do we need an addition router to perform this task. scope
changes.

If your increasing the subnet, you do not need another router. You will have
to change the subnet mask on every device though.

I didn't post earlier,..but the whole thing is a bad idea from the
beginning. You should keep the number of Hosts per segment down below 300.
A straight 24bit mask does this fine. You should divide the system up into
254-host subnets (24bit mask) and use a LAN Router or Layer3 Switch between
the segments.

-----Router 192.168.1.254 255.255.254.0-------
-----------switch----------
^
----192.168.0.x-----------------192.168.1.x
^
DHCP Server 192.168.0.100 255.255.254.0 Default gateway
192.168.1.254
Current Scope 192.168.0.1-192.168.1.254
So you are saying 4 seperate scopes
192.168.0.x 255.255.255.0
192.168.1.x 255.255.255.0
192.168.2.x 255.255.255.0
192.168.3.x 255.255.255.0
And change the router to 192.168.1.254 255.255.255.0 ?

No, You need a router that has four LAN interfaces, each one having a
different subnet. For example eth0 is 192.168.0.0, eth1 is 192.168.1.0, etc.
For devices on one subnet to talk to devices on another subnet, it has to go
through the router.
