Subnetting Example: Before
Subnetting
You can ―borrow‖ one of the host ID bits to divide the network 192.168.1.0 into two separate sub-networks. The subnet
mask is now 25 bits (255.255.255.128 or /25).
The ―borrowed‖ host ID bit can have a value of either 0 or 1, allowing two subnets; 192.168.1.0 /25 and 192.168.1.128 /25.
The following figure shows the company network after subnetting. There are now two sub-networks,
A
and
B
.

Subnetting Example: After
Subnetting
In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 2
7
– 2 or 126 possible hosts (a host ID of
all zeroes is the subnet‘s address itself, all ones is the subnet‘s broadcast address).
