IT-320 Chapter 5
IP Addressing
Objectives• 1. Identify Ipv4 and Ipv6 addresses and their default subnet masks.• 2. Identify the differences between public and private networks.• 3. Identify the purpose of subnetting and default gateways.• 4. Given an IP address and subnet mask, determine the network and
host addresses.• 5. Given a network situation, determine the subnet mask for that
network.• 6. Explain the difference between Classful IP and CIDR addressing .• 7. Explain VLSM and CIDR.• 8. Identify the purpose of NAT services as compared to a Proxy
server.• 9. Identify the purpose of subnetting and default gateways.• 10. Given a range of networks, aggregate them to the highest degree
possible.• 11. Specify the main features of Ethernet, Token Ring and FDDI.• 12. Specify the speed, length, topology, and cable characteristics for
Ethernet.• 13. Build an Ethernet network.
