Video Description

Classless IP Addressing (part 2) In this lesson we further break down subnet masking by examining what happens when we change the last octet of our IP address to create deeper layers further that our subnet mask when expanding the network. We'll diagram and breakdown the calculation to demonstrate who you calculate out in bits the subnet mask when the last octet is already a subnet masked IP address.
