Networking 101 : Subnets, masks and IP addresses - C class example -
We are using for our example a class C network IP address - 192.168.1.0 -.
Because it is a class C address the first three octets - 192.168.1 - are used for the network address.
The IP addresses for our example go from - 192.168.1.1 - to the broadcast address -192.168.1.255 -
We could have 254 machines in our network.
For our example, we will use the standard "24" mask as below:
To know the network part, we take into account the bits
that have a value of “1” for both the IP address and the subnet mask.
According tour above example, the network part is : "192.168.1"
The first IP address refers to the network - 192.168.1.0 - and the last IP address refers to the broadcast address -192.168.1.255 -.
