Session 7: Representation of network addresses
In previous sessions you have learned how to recognise IP addresses and MAC addresses. In this session you are going to take a closer look at how these addresses are represented. You will be looking at two different number bases – binary and hexadecimal – and how they can represent the addresses used in network communications. Then you’ll move on to have a closer look at subnet masks.
By the end of this session, you will be able to:
- use the binary and hexadecimal number base systems and convert between different number bases using a calculator
- express a subnet mask in Classless Inter-Domain Routing (CIDR) notation
- recognise the role of CIDR in the scalability of communication networks.
