Changing LAN subnet mask
Hi I would need help from the experienced experts here . We will be changing our LAN subnet mask in the next couple of weeks. We have user workstations, servers and networking equipment in this subnet. We currently have a 192.168.0.0/24 network and we'd like to extend it to a /23 or /22. I know I'll have to change the DHCP scope, firewall, servers, etc. But my question is, where do I start? Should I start with the clients or the L3 switches, configure the static IP information on the servers... Is there a "best practice" on how to do this? Of course we won't do this during work hours.
