I have a 172.16.2.1 / 255.255.255.0 range currently that is running out of IP addresses. If I am understanding correctly, in order to allow for more IP addresses I.E. 172.16.3.0, all I need to do is change the subnet mask on all devices to 255.255.254.0? So, any device with static IPs would need to changed...Just trying to make sure we do everything correctly in the correct order. Do we change our AD servers first? Change on our firewall?
