I am currently in the mist of planning out a new network design for a building move, however I was not 100% on best practices.
We currently have roughly 200+ servers, and roughly 600 users in our current location. We want to plan a building with 8% user growth per year, over the next 10 years. We are also going to be adding a VoIP system into this new location, which we currently do not have.
Taking a looking at my estimations, that would be roughly 1900 (500 server + 700 user + 700 VoIP) IP's, which I would like to grow into.
We currently have a 10.0.0.0/16 network, which seems like severe over-kill. I was considering looking at a 172.16.0.0/32 or /16, however after reading some of the posts here, it looks like I should be trying to keep around 100-200 hosts in each subnet? In my head I was thinking of breaking up the subnets by Geographical Location, but maybe I should be looking into breaking it up into departments?
As stated above, I was hoping someone could give me some insight/direction on best practices, as I feel like I am barking up the wrong tree with my /32.
