Somewhere along the line I must of forgetten my rules for subnetting, or perhaps I enjoyed my recent vacation too much. At any rate this is situation I’m in right now…
My 100 node network is current just a static class C address (192.168.1.0). We have telecom installers for a new VOIP system coming Wednesday and they asked me to provide them a full 254 ip’s (one full subnet). I didn’t think this would be a problem, I’ve done this before in the past. However, two fellow employees (who are higher than me on the corporate organization chart) are possessed with the notion that I can simply subnet a class C and therefore have two subnets (the original 192.168.1.x plus the “new” one) and BOTH will provide for 254 addresses.
Now I’ve done my little subnet scribbling on a piece of paper and I double checked with a subnet calculator — there’s no way I’m coming up with a CLASS *C* subnet strategy that provides for *2* 254 address subnets. (I show 2 subnets at 126 each).
Am I’m confused or insane?
