48.Explain the concept of subnetting the network.
Ans.
1. Every IP network has two addresses that cannot be used –The network IP number itself and the broadcast addresses.
2. Every time we subnet we are creating these two unusable addresses, so the more subnet we have, the more IP addresses we lose.
3. We need to determine the subnetwork mask and network numbers. Subnetworking takes one or more of the available host bits and makes them appear as network bits to the local interfaces.
4. If we want to divide our Class C network into two subnetworks, we’d change the first host bits to ones, and this would give us a net mask of 255.255.255.192
5. Lastly, assign the appropriate numbers for the network, the broadcast address, and the IP addresses for each of the interfaces.
