Answer:
Introduction
uSoft.com is a software development company with two branches spread over the Gold Coast region. Thy are currently use a basic local area network for communication with each branches. They have total three different branches. Head Quarter has total of 100 network devices and branch A and branch B has total 30 and 20 network devices. They have been assigned with a new IP address. Therefore, they want to re design the network and create a proper IP addressing schema for their office by utilizing the new IP address. This report consists the IP sub-netting, IP addressing range, broadcast address, subnet musk. They want this IP addressing schema in both IPv4 and IPv6 way. This repot also include the detail network design for the uSoft.com.

From the above sub-netting table, it can be analyzing that the total six different subnets are used where total three subnets are used for their branch office and last subnet is used for the routers those are connected with the branches. Key IP address for this network are the available IP address range. This IP address can be used to configured any network devices.

Conclusion
The above network design and IP sub-netting schema is designed for uSoft.com. The IP addressing schema will work properly for the organization. Total 6 different subnets are created. Main three subnets are for all offices including the headquarter and other two branch offices. Another three subnets are used for router configuration. From the above IP addressing schema, it can be concluded that the IP address perfectly designed for the uSoft.com.
