Hi,
My friend has told me that we can use subnetting in class C i.e we can have 192.168.0.0/20 network.I am not not convinced as Class C have three octets of network and one octet for hosts.My friend says that class C private range is from 192.168.0.0 to 192.168.255.255 and hence we can subnet in third octet as well.I am not convinced please clarify my confusion whether we can subnet in 3rd octet of class C private address scheme or can we have 192.168.0.0/20,192.168.0.0/22,192.168.0.0/18 etc network scheme.
