Question

****** Result for Image/Page 1 ****** 1. (15 marks) You are helping set up a network for a new organization. The organization has 3 sites and you are given the below diagram You are required to set up the network using subnets of a single FIXED size. There are 7 machines connected to S1, 29 connected to $2, and 17 connected to S3. PC-D PC-C S2 G0/1 PC-F sofo/1 PCA $0/0/0 2 PC-B PCE S0/0/0 S0/0/1 G0/1 SO/0/0 GO/1 s3 SO/0/1 The 192.168.151.0/24 network address is used to provide the addresses in the network. o Determine the number of subnets in Network Topology. o How many subnets are there? o How many bits should you borrow to create the required number of subnets? o How many usable host addresses per subnet are in this addressing scheme? o What is the new subnet mask in dotted decimal format? o How many subnets are available for future use? o Record the subnet information. o Create a table with the columns, as shown below, and fill in the required subnet information. Subnet Number Last Usable Host First Usable Host AddressS Network Address Addresss Broadcast Address 2. (13 Marks) After completing the required task, you decided to show the organization's management how much more efficient Variable Length Subnet Masking would be. Repeat the network IP allocation completed in Question 1 but utilize Variable Length Subnets (VLSM) to most efficiently. 3. (2 marks) How much more efficient is the solution to Question 2 and than Question 1. 4. (10 Marks) Repeat question 1, using IPv6 addressing. You have the global prefix 2001:DB8:DAD:/48 to use to create your network.

Answer 1

Major Network: 192.168.151.0/24
Available IP addresses in major network: 254
Number of IP addresses needed: 53
Available IP addresses in allocated subnets: 74

Subnet Name	Needed Size	Allocated Size	Address	Mask	Dec Mask	Assignable Range	Broadcast
A	7	14	192.168.151.64	/28	255.255.255.240	192.168.151.65 - 192.168.151.78	192.168.151.79
B	29	30	192.168.151.0	/27	255.255.255.224	192.168.151.1 - 192.168.151.30	192.168.151.31
C	17	30	192.168.151.32	/27	255.255.255.224	192.168.151.33 - 192.168.151.62	192.168.151.63
