Someone was asking me a question about a network that had unmanaged switches on it. Can you use two different IP ranges on this network. Example 192.168.1.12(this could be any range of number for the last number.)and then on the same network/switches 184.108.40.206(there again the range of the last number could be any number) I told them that this could cause issues. Is this true and if so can you directed me to a web page that would explain it.) This network is not on the internet at all. Let me know if any other details are needed.
