I have site that is using 192.168.201.0 w/subnet mask 255.255.255.0
There is a windows 2003 SBS domain and the PDC is handling DNS and dhcp.

They also have a router in the building offering public wifi.
For the public wifi I have the router's wan port on the 192.168.201.0 subnet and it acts as a dhcp server to the public clients on a different subnet.

This business is wanting to cover a larger area with wifi. They want wifi to be available for both public and private users, employees

After looking into access points I think I'm going to go with ubuiti unifi pro.
It has up to four SSID's. I could allow public users to an SSID defined as "guest" and turn on client isolation for guest. Private users could connect to their own SSID and be isolated from guests.
I would still use the 2003 SBS as DHCP, only problem is that because of the way ip addressing and the dhcp scope was originally set up I'm kinda restricted on ip address to put into the scope.

So what I'd like to do is change the subnet mask to something else that would allow for more ip addresses. Maybe even something like 255.255.128.0

This would allow me to have a very large pool of ip addresses available for guest computers.

Is doing this as simple as changing subnet masks on my server, router's lan, computers/devices with static ip's and doing a release/renew on dhcp clients?
