Q1: Network Addressing Scheme (FIXED LENGTH SUBNETTING) Minimizing Hosts/Subnet In this assignment, you will be subnetting the network 121.0.0.0 to design a network addressing scheme for a company expanding to new locations. You will see two subnetting approaches: fixed-length subnetting (without VLSM) and variable length subnet masking (VLSM). Fixed length Subnetting: When subnetting without VLSM, you apply the same subnet mask to all subnets. This creates fixed-size subnets, which may result in some IP address waste if subnets need different numbers of hosts. Variable length Subnetting: VLSM allows you to assign different subnet masks to subnets based on their specific host requirements, conserving IP addresses. (We'll apply this approach in Q3.) For Q1, you are tasked to design a network without VLSM to meet the following requirements: a. Minimum Hosts per Subnet: Each fixed-length subnet should support the minimum number of hosts necessary based on the network's specifications (as seen in the figurebelow). b. Growth Allowance: Ensure that each subnet has enough additional capacity to accommodate a 90% increase in hosts across all areas to allow for future expansion. c. Fixed Length Subnet Masking Gharrafa 2500 IP address 121.0.0.0 S 0/0/0 S 0/0/1 F 0/1 F 0/0 S 0/0/1 S 0/0/0 Router F0/0 S 0/0/1 Doha 1500 For the figure on the previous page, and for the information given in Q1, answer thefollowing questions: Address class Custom subnet mask Minimum number of subnets needed Extra subnets required for 90 % growth +(Round up to the next whole number) Total number of subnets needed = Number of host addresses in the largest subnet group Number of addresses needed for 90% growth in the largest subnet + (Round up to the next whole number) Total number of address needed for the largest subnet = Start with the first subnet and arrange your sub-networks from the largest group to the smallest: Subnet 1: IP address range for Doha Subnet 2: IP address range for Gharrafa Subnet 3: IP address range for Router A to Router B serial connection Subnet 4: IP address range for Router A to Router C serial connection Subnet 5: IP address range for Router C to Router D serial connection Q3: Refer to Q1. Using Variable Length Subnet Masking (VLSM), design a network addressing scheme that minimizes the number of hosts per subnet for each connection between the routers. Your goal is to provide IP addresses for the 3 WAN connections between Router A-B, Router A-C, and Router C-D while conserving IP addresses by allocating only the necessary host counts foreach link. a. Subnet Mask with VLSM: Choose the most efficient subnet mask for each WAN link to accommodate the minimum number of hosts required on each connection. b. IP Address Ranges with VLSM: Specify the IP address range allocated to each WAN link: 。 Router A to Router B serial connection o Router A to Router C serial connection 。 Router C to Router D serial connection C. Freed IP Addresses: Calculate the total number of IP addresses saved by using VLSM for each connection compared to using a fixed-length subnet mask that would cover the largest host requirement. IP addresses saved on Router A-B link by applying VLSM (compared to Q1): IP addresses saved on Router A-C link by applying VLSM (compared to Q1): IP addresses saved on Router C-D link by applying VLSM (compared to Q1): Total Addressed Saved by VLSM on all WANS (compared to Q1) d. Reflection: In 2-3 sentences, explain how is it advantageous to allocate only the necessary number of hosts on WAN links, especially in larger networks? Reflect howthis allows for more efficient IP allocation in network segments with different host requirements.
