We have two buildings in close proximity to eachother, that are currently connected by fibre.
We are experiencing an issue with network capacity at the moment, the organisation is using a class C address range the the vast majority of network devices, and we are now running out of IP addresses.
The ideal situation would be to move over to a class B address range, which we can subnet for various departments/services.
My networking a little rusty...but I'm thinking in order to accomplish this, we would need two routers, one for each building, connected together. That way they can route internally to various subnets to either building. Is this correct? Someone has mentioned to me that I would only need one router, but I'm not too sure on how that would work...
