I haven't had to deal with thinking about subnets in about 10 years and so I am rusty and need some help that I can't find an answer to:
Current setup: DHCP server 192.168.11.150, gateway 192.168.11.1, subnet 255.255.255.0
I need more IPs, so I want to change the subnet to 255.255.254.0 on my switches, wireless APs, firewall, and DHCP server. I would need to either delete and make a new scope or create a superscope on the DHCP server (Windows Server 2012).
Questions: can I leave all of my old/legacy devices with the 255.255.255.0 subnet and still get access to the DHCP server and general internet? Can any of those legacy devices see any new devices connect to the network and can the new devices see the old ones with the different subnets?
Thanks!
