Background

Networks are segmented using routers, which limit broadcast domains, and allow data to flow from network to network. The key features of network configuration are:

1. UNIQUE IP ADDRESSES. All IP addresses on the Internet must be unique.
2. NETWORK ADDRESS MUST BE UNIQUE, AND RELATE TO THE ALLOCATED ADDRESSES.
3. ROUTER PORT MUST BE SET. The router port should be set for the subnet which the port connects to.
4. SUBNET MASK MUST BE SET CORRECTLY. The subnet mask must be correctly set for the required structure.
5. GATEWAY ADDRESS MUST BE SET. The gateway address must be setup on each node. This is normally the port on the router to which the node connects to.
6. NETWORK ADDRESS MUST NOT BE USED FOR A NODE. The host part of the address must not be all 0's.
7. BROADCAST ADDRESS MUST NOT BE USED FOR A NODE. The host part of the address must not be all 1's.

Challenge 03

The network architecture in Figure Ch3.1 has been allocated the Class B address of 146.176.0.0. A subnet mask of 255.255.255.0 has been selected, and the subnet addresses are: 146.176.140.0, 146.176.150.0, 146.176.175.0, 146.176.160.0, 146.176.165.0 and 146.176.166.0. Determine the configuration errors, and their type:
