Supernetting 140.128.0.0 (10001100 10000000 00000000 0000000 0
Since this is a class B starting address, the subnet mask indicates that 5 out of 8 bits in the next octet are being used for subnetting. This gives a maximum of 30 possible subnets.
If you aren't subnetting, the network address is 13.0.0.0
SUBNET: subnet is a group of networks having same network id. subnet increase the number of hosts with same network address, as result it reduces the wastage of addresses. In subnetting bits of hostId will be captured by networdId. SUPERNET: supernet makes all the hosts with in a range of network address belong to a same group. This reduces the entries in the network address table. Supernetting combines the octets of the address.

Yes. Subnetting separates a network into multiple logically defined segments, or subnets.
No, because first three octets are suppose to be same and they are not.
Definition: A subnet is a logical grouping of connected network devices. Nodes on a subnet tend to be located in close physical proximity to each other on a LAN.The pourpose of subnetting is not to provide extra addresses, but to keep network data separated to prevent congestion.
There is no need to use subnetting if you have no wish to further divide up your network into smaller, logical networks.
Subnetting is the practice of dividing a network into two or more networks.
