What’s Wrong With These Addresses: (When used to address hosts on a network – not all are invalid.)

Recommended Process Identify Address Class of Address Review of Addressing Rules: Valid Binary Converted Decimal Numbers Class A, B and C Address Ranges Complete Network ID or Host ID cannot be all 0’s or 1’s (in binary).

Subnetting/Addressing There will be three scenarios in this project. You will be subnetting an IP network address. You will then apply addressing information to the diagrams accompanying the subnetting problem. Each diagram will have different devices in them. You will apply addresses to the devices that need them. You will also identify Broadcast domains and Collision domains. We will begin with a Class A address and then you will have 2 Class B addresses. The next Project will have students using VLSM/CIDR.
