Learn IPv4 subnetting Part 2
Here is how we would continue numbering our host addresses for a class-B IPv4 address using the .0 sub-network as an example.
Network address: 122.100.0.0 Broadcast address: 122.100.63.255
Host address range: 122.100.0.1 thru 122.100.62.255
Example: After we number all the way up to 122.100.0.255 the third octet’s zero becomes a 1 and the 255 rolls over to become a 1 and the numbering begins again: 122.100.1.1 thru 122.100.1.255, and then the two numbers roll over again to become 122.100.2.1 thru 122.100.2.255, and so on.
For a class-A address we would be numbering across three octets instead of two. So, you can see how huge class-B and class-A networks are!
I hope that helps
