Currently we have been assigned two consectutive subnets on a B Class network (220.127.116.11 and 18.104.22.168). The 22.214.171.124 subnet is our primary network and is assigned a 255.255.255.0 netmask. The 126.96.36.199 subnet has been divided up into smaller variable sized subnets (we have 188.8.131.52/30, we have 184.108.40.206/29 and 220.127.116.11/29 and 18.104.22.168/28 ) by my predecessor. The 22.214.171.124 subnet currently is at 80 % capactity, and the only addresses used on the 126.96.36.199 subnet are the ones I indicated above.
My problem is as follows, we are moving to a larger building and at the same time are increasing the number of PC's on the network. My initial plan was to utilize the unused first portion of the 188.8.131.52 subnet for these new pc's in the new building and keep the existing pc's on the 184.108.40.206 subnet and when ready to move completely into the new building take the network down in the old building and move it to the new building all in one fell swoop. Unfortunately my supervisors don't want the network down at all and want to move people and pc's one office at at time over a 6 -8 month period as the new building gets finished. So now I will have some pc's on the 220.127.116.11 in both locations and the 18.104.22.168 pc's in the new building only, but all will need to access the internal networks and connect to the external networks as well. I only have three Cicso 3640 routers to work with to get this setup done. One being a spare and the other two connecting us to three seperate networks at other company locations. I will be using the spare router in the new building as an initial connection to the existing network, I have looked into the "Supernetting Idea" which sounds like it will do what I want it to do, but am not sure if this will work with my setup, especially the variable subnets on the 22.214.171.124 subnet. Does anyone out there have any suggestions or experience with supernetting that could help me figure this out?
