A subnet mask is used to identify which parts of the ip
address are the network parts and which parts are the host
parts.
e.g
IP 192.168.1.10
Subnet mask : 255.255.255.0
This indicates that the first 3 parts of the IP address are
used to identify the Network.
Let's take a class C mask of 255.255.255.0 - If we borrow 2
network bits, the mask changes to 255.255.252.0, this is
called Supernetting. If on the other hand we borrow two host
bits, the mask changes to 255.255.255.192, this is called
subnetting.
Supernetting therefore allows you to have more hosts on one
network, whilst subnetting allows you to have more inter
networks but with less hosts.
.... So without subnetting or supernetting these two
addresses would be on same network:
IP 192.168.1.10
Subnet mask : 255.255.255.0
IP 192.168.1.233
Subnet mask : 255.255.255.0
With Subnetting, we have borrowed one bit (from the host
part) which in binary looks like this 1000000, now this
splits the network into two networks so these addresses are
now on different networks.
IP 192.168.1.10
Subnet mask : 255.255.255.128
IP 192.168.1.233
Subnet mask : 255.255.255.128
With Supernetting, we borrow one bit from the network part
so the last two parts of subnet mask now look like this
11111110.00000000. These two are on the same network now
because the number of host addresses has increased.
IP 192.168.1.10
Subnet mask : 255.255.254.0
IP 192.168.2.125
Subnet mask : 255.255.254.0
