- • IPV6 addresses use 128 bits to represent an address which includes bits to be used for subnetting. The second half of the address (least significant 64 bits) is always used for hosts only. Therefore, there is no compromise if we subnet the network. Use the Figure below to Create five subnets using route prefix 2001:db:acad::/48 (1 Marks) Routing Prefix Subnet ID Interface ID 48 Bits 16 Bits 64 Bits19. ARP is used for: O packet path determination O finding of a mapping IPV6 → MAC address O finding of a mapping IPV4 → MAC address O finding of a mapping IPV4 → TCP addressSUBNET ADDRESSING Consider the router and the two attached subnets below (A and B). The number of hosts is also shown below. The subnets share the 23 high-order bits of the address space: 144.145.110.0/23 : A 175 hosts QUESTION 2 OF 10 Answer How many hosts can there be in this address space? 144.145.110.0/23 B Assign subnet addresses to each of the subnets (A and B) so that the amount of address space assigned is minimal, and at the same time leaving the largest possible contiguous address space available for assignment if a new subnet were to be added. Then answer the questions below. 84 hosts
- 1.4-10 Link Utilization (a). Consider the scenario below where 4 TCP senders are connected to 4 receivers. The servers transmit to the receiving hosts at the fastest rate possible (i.e., at the rate at which the bottleneck link between a server and its destination is operating at 100% utilization, and is fairly shared among the connections passing through that link). Server-1 Host-1 Server-2 Rs Rc Server-3 Rs Rc Rs R Rc Host-3 Server-4 Rs Rc Host-4 Host-2 Suppose that R = 1 Gbps and Rc is 300 Mbps and R, is 200 Mbps. Assuming that the servers are sending at their maximum rate possible, enter the link utilizations for the client links (whose rate is Rc) below. Enter your answer as a decimal, of the form 1.00 (if the utilization is 1, or 0.xx if the utilization is less than 1, rounded to the closest xx). The utilization of the client links, whose rate is Rc, is: [A]Question 9 Convert the following IPv4 address into dot decimal address, and determine which type of these addresses are. a) 10000001 00001011 00001011 11101111 b) 11000001 10000011 00011011 11111111 c) 11100111 11011011 10001011 01101111 Computer network Full explain this questionYou are hired to design and manage a network of a company. The topology of the network is shown above. The Internet Service Provider (ISP) provides the following information to connect the corporate network to the Internet. The CIDR range given for the company: 124.34.52.0/21 The address of the ISP router (also called "Gateway address"): 124.34.63.254 Configure the network by giving CIDR blocks for each company subnet and IP addresses for each station and router knowing that: For Ethernet 1, we need 514 hosts to connect. For Ethernet 2 we need 50 hosts to connect. For Ethernet 3 we need 123 hosts to connect. For the Token Ring network we need 132 hosts to connect. You need to take into account the gateway addresses that need to be allocated for each of the subnets. Assign IP addresses to hosts A, B, C and D and IP addresses to the router gateway interfaces.

- SUBNET ADDRESSING Consider the router and the two attached subnets below (A and B). The number of hosts is also shown below. The subnets share the 23 high-order bits of the address space: 144.145.110.0/23 175 hosts QUESTION 3 OF 10 A Answer What is the subnet address of subnet A? (CIDR notation) 144,145.110.0/23 Assign subnet addresses to each of the subnets (A and B) so that the amount of address space assigned is minimal, and at the same time leaving the largest possible contiguous address space available for assignment if a new subnet were to be added. Then answer the questions below. B 84 hosts4 LANS are connected to a router (R1) with each LAN compares of several hosts connected to a switch. Each LAN cotains the following number of hosts (end devices and the gateway interface), • LANI à 30 Hosts • LAN2 à 15 Hosts • LAN3 à 20 Hosts • LAN4 à 3 Hosts You have received the address space 200.16.1.0/24. Use the address space to create a subnetting scheme of four subnets with equal size in a way to accommodate the number of hosts required. Consider the following points in your answer, / Explain the procedure of your subnetting scheme / Highlight the suitable prefix and the subnet mask / Highlight the number of wasted hosts in each subnet after determining the most suitable prefix / Use the table below to provide the subnet details for each LAN Subnet Address First Host address Last Host address Broadcast address 1 LANI 2 LAN2 3 LAN3 4 LAN423. Consider a datagram network using 8-bit host addresses. Suppose a router uses longest prefix matching and has the following forwarding table: Prefix Match 00 01 100 otherwise Interface 0 1 2 3 For each of the four interfaces, give the associated range of destination host addresses and the number of addresses in the range.
- 2. As a newly hired network engineer, you are tasked to compute for addresses of a newly developed network. Use 129.152.224.0/22 to compute for the subnets using VLSM method. Fill up the information in this table Required Number of Bits Borrowed Number of Host 100 Department A Department B 60 Department C 10 Department D 4 Department E 12 Department F 30 Department G Department H 10 Department I 8 Department J Department K 55 15 25 New Subnet Mask Prefix Subnetwork Number of Host Created Wasteq no 5: In the above network diagram, IP and MAC addresses are given for network nodes. Suppose Host1 (Shahid) sends a datagram to Host2 (Khalid). What IP and MAC addresses (source and destination) will be written in IP and Data link layer headers respectively, for the following intermediate points from Host1 to Host2? Host1 to Router1 (R1) Router1 to Router2 (R2) Router2 to Host2An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most signi cant bits are used as a network ID, and the 16 least signi cant bits are used as a host ID. However, the host ID cannot be all 0's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network?
