What is Subnetting
Subnetting is a way of partitioning a network at the IP level by dividing a block of addresses into a number of smaller sets.
To understand what is happening, first look at some small numbers rather than a full IP address.
Take the set of 'addresses' 100 to 129.
If computers used decimal representation, this network of 30 addresses might naturally be split into:
100 - 109
110 - 119
120 - 129
The first two digits represent the subnet number (10,11,12), while the final digit gives the address within the subnet.
