Hi, I need to extend an existing Class C network (192.168.0.0/24) to allow about 3-400 hosts.
Is it ok to set the subnet mask to /23 (thus allowing 510 hosts) but keep the IP numbers in the 192.168.x.x range?
I would get the usable range 192.168.0.1 to 192.168.1.254 but I dont know if that is 'legal' in a local addressing scheme.
Would it be better to switch to a 172. or 10. scheme? I would rather keep it at 192.168.x.x so that devices with fixed IP's don't need configuring.
Bit rusty with all this Networking gubbins :)
