TaskIn your role as a Solutions Architect at M2M Solutions, you are leading a team of several system administrators. M2M solutions is a medium sized organisation and is currently expanding its operations.The company has acquired six sites across Sydney to accommodate its various departments.You have been asked to design a network by utilizing XXXXXXXXXXprivate IP address. The network should span six buildings with a router in each building to join the networks. It is assumed that each building will have its own single subnet .Company expects approximately 1200 workstation across all the sites with approximate numbers in each building as follows:Finance Office - 260 workstationsTransport Office - 130 workstationsResearch Office - 120 workstationsSales Office - 40 workstationsInformation technology - 520 workstationsHead Office - 60 workstationsTASK 1 -Write a 1000 words (+/- 10%) report explaining:a.The detailed design of a simple addressing solution (with diagram(s) and step by step workout of the calculations) that leaves room for growth, is easy to administer and has the minimum wastage of available IP address space.b.Explain what happens to your design if the number of hosts per network jumps to over 1,024 per building.TASK 2 - Currently the company policy does not allow the use of network analysers on the organisational network. You have recently had a team meeting where all the staff are of the view that the use of network analysers can bring more efficiency in troubleshooting processes.Write an 800 words (+/- 10%) report for the board of directors proposing to allow the use of network analysers for diagnostic purposes in new proposed network architecture. Your report should include:a. Brief explanation of protocol in the context of communication networks and the role of network analysers. Explanation should include example of a situation where network analysers can be used in the context of Task 1.b. An analysis of currently available network analyser tools. The analysis should contain:i. Benefits, associated costs, ease of usabilityii. Recommendation from you, as to what tool would you prefer to use and why.(The reports should be targeted towards your audience i.e. the board of directors who may not be technologically savvy. Therefore the report should be easy to read and contain step by step overview of the design that includes calculations and assumptions.Additionally, the report contencts should be logically, systematically and succinctly structured to create a cohesive and coherent analytical piece of work, using formal academic language and should adhere to grammatical conventions.)

Part 1. a. Network Design and Scheme of Addressing  
The mentioned company has six offices in different buildings in the city Sydney. The 
infrastructure of the network is not configured for the company for its all 6 offices of the 6 
different buildings. Therefore, a network design for its all six offices is first required and then 
addressing scheme is employed to provide an local IP address for the network communication 
among the workstations and other network devices including the Internet communication. The 
proposed network design for the company is presented in figure 1. 
Figure 1. Company Network Layout for its All Six Office Buildings
The IP address 10.0.0.0 is allocated for the company. This IP address is private IP address as first 
decimal value from first octet is 1. The workstations and other devices of the company network 
need an IP address to communicate with others and Internet. The simple IP addressing scheme is 
to consider the network bit and host bit from 32 bits of given IP address. As, private IP address 
10.0.0.0 is a class A IP address so that by default the net bits for class A IP address is 8 and host 
bits are 24. But, to locally distribute the IP addresses to the workstations of the offices of 
company a masking scheme is required to mask the given IP address to provide the IP address. In 
the process of subnetting and masking we take host bits to provide the required number of hosts 
for an office as mentioned. 
The calculation of masked IP address with respect to host bits is 2^ 
No of host bit
. Thus the required 
number of IP addresses for workstations under the mentioned offices are as follows. 
 Finance Office : Total number of workstations = 260. Therefore the host bits is calculated 
as 
2^ 
host bits
 >= 260 
2 ^
9
 > =160 
Thus, host bits = 9 
Total No. of IP addresses will be 512 – 2 = 510. For finance office total number of usable 
IP addresses are 510.  
The required IP addresses for the workstations are 260 but 510 usable IP addresses 
available with taken host bits. Therefore, 510 – 260: 250 IP addresses will be free under 
the subnet of Finance office. 
 Transport Office : Total number of workstations = 130. Therefore the host bits is 
calculated as 
2^ 
host bits
 >= 130 
2 ^
8
 > =160 
Thus, host bits = 8 
Total No. of IP addresses will be 256 – 2 = 254. For transport office total number of 
usable IP addresses are 254.  
The required IP addresses for the workstations are 130 but 254 usable IP addresses 
available with taken host bits. Therefore, 254 – 130 : 126  IP addresses will be free under 
the subnet of transport office. 
 Research Office : Total number of workstations = 120. Therefore the host bits is 
calculated as 
2^ 
host bits
 >= 120 
2 ^
7
 > =160 
Thus, host bits = 7 
Total No. of IP addresses will be 128 – 2 = 126. For research office total number of 
usable IP addresses are 126.  
The required IP addresses for the workstations are 120 but 126 usable IP addresses 
available with taken host bits. Therefore, 126 – 120: 6 IP addresses will be free under the 
subnet of research office. 
 Sales Office : Total number of workstations = 40. Therefore the host bits is calculated as 
2^ 
host bits
 >= 40 
2 ^
6
 > = 40 
Thus, host bits = 6 
Total No. of IP addresses will be 64 – 2 = 62. For sales office total number of usable IP 
addresses are 62.  
The required IP addresses for the workstations are 40 but 62 usable IP addresses available 
with taken host bits. Therefore, 62 – 40 : 22 IP addresses will be free under the subnet of 
sales office.
 IT Office : Total number of workstations = 520. Therefore the host bits is calculated as 
2^ 
host bits
 >= 520 
2 ^
10
 > = 520 
Thus, host bits = 10 
Total No. of IP addresses will be 1024 – 2 = 1022. For sales office total number of usable 
IP addresses are 1022.  
The required IP addresses for the workstations are 520 but 1022 usable IP addresses 
available with taken host bits. Therefore, 1022 – 520 :
