- How does IPv4 Subnetting Work? 8 answers
I'm currently learning about IPv4 and subnetting. As far as I understand, if we want to create 4 small isolated networks with the size 50, we can use subnetting.
If we subnet a Class-C IPv4 network(
184.108.40.206) into 4 small networks with the same size (
192~255), these small networks are still essential belonged to the big logical network (
220.127.116.11) even though we assign subnet masks to them.
If I understand correctly, they can communicate with each other since they share the same network portion. So, in practice, how can we isolate these small networks?
