What happens if you have more than one IP subnet in the same VLAN?
If you have hosts from more than one IP subnet in the same VLAN, you defeat the purpose of VLANs, as the two (or more) subnets will be on the same broadcast domain.
How are the subnets of a network broken up?
Right now, our network is broken up via subnets: production, management, intellectual property (IP), etc., each on a separate subnet. Would creating VLANs instead of subnets be more beneficial? Our general goal is to prevent bottlenecks, separate traffic for security, and to manage traffic with more ease.

How to separate a Class C network into two VLANs?
Let’s say I have a class C network 192.168.0.0 and have hosts from 192.168.0.1 to 192.168.0.50, and they are all connected to a switche. If I want to separate the hosts on this network into 2 VLANs, I would change the VLAN setting on each ports.
