Assign network addresses to each of these six subnets,with the following constraints: All addresses must be allocated from 212.10.8/23; Subnets A, B, and C should have enough addresses to support 120, 240, and 120 interfaces respectively. Of course, subnets D, E, and F should each be able to support two interfaces. For each subnet, the assignment should take the form of a.b.c.d/x or a.b.c.d/x - e.f.g.h/y. Using your answer to the previous part, provide the forwarding tables (using longest prefix matching) for each of the three routers. You may use label R1A to denote the interface on router R1 that is part of subnet A and so on.

. Consider a network with prefix 182.168.56.128/26. Give an example of one IP address (of form xxx.xxx.xxx.xxx) that can be assigned to this network. Suppose an ISP owns the block of addresses of the form 170.168.56.64/26. Suppose it wants to create four subnets from this block, with each block having the same number of IP addresses. What are the prefixes (of form a.b.c.d/x) of the four subnets?

q 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 Host2
Assume that a large number of consecutive IP addresses are available starting at 198.16.32.0 and suppose that two organizations, A, B, C, and D, request 1000, 3000, 2000, and 4500 addresses, respectively, in that order. For each of these, give the first possible IP address within the assigned subnet, the last possible IP address within the assigned subnet, and the subnet representation in slash notation (w.x.y.z/s). In the imagine I have the answers but I am very confused on how to get them. Specially after A and B I do not undertand how the initial address of C is 198.16.64.0 how did that 64 happen??? Please explain all in detail. Thank you!
Suppose an ISP owns the block of addresses of the form 126.120.40.64/26. Suppose it wants to create four subnets from this block, with each block having the same number of IP addresses. Now answer the following: a. What is the maximum number hosts each subnetwork can have? b. What are the subnet addresses (of form a.b.c.d/x) for the four subnets? c. What is the first usable IP address of first subnet? d. What is the broadcast address of first subnet? e. What is the last usable IP address of first subnet?
Consider a router that interconnects three subnets: A, B, and C. Supposeall of the interfaces in each of these subnets are required to have the prefix212.1.104.0/21. Suppose subnet A is required to support 1000 interfaces, andsubnets B and C are each required to support 500 interfaces. Provide networkaddresses for A,B and C (in the form a.b.c.d/x) that satisfy these constraints. Model Solution: E.g.: A: 212.1.104.0/22B: 212.1.108.0/23C: 212.1.110.0/23 Can you explain how it comes this model Solution
A large number of consecutive IP addresses are available starting at 198.16.0.0. Sup- pose that four organizations, A, B, C, and D, request 4000, 2000, 4000, and 8000 ad- dresses, respectively, and in that order. For each of these, give the first IP address as- signed, the last IP address assigned, and the mask in the w.x.y.z/s notation. A router has just received the following new IP addresses: 57.6.96.0/21, 57.6.104.0/21, 57.6.112.0/21, and 57.6.120.0/21. If all of them use the same outgoing line, can they be aggregated? If so, to what? If not, why not? The set of IP addresses from 29.18.0.0 to 19.18.128.255 has been aggregated to 29.18.0.0/17. However, there is a gap of 1024 unassigned addresses from 29.18.60.0 to 29.18.63.255 that are now suddenly assigned to a host using a different outgoing line. Is it now necessary to split up the aggregate address into its constituent blocks, add the new block to the table, and then see if any reaggregation is possible? If not, what can be…
An enterprise wants to use a network infrastructure that complies with the class B IP addressing template given below. The network part of this is the internet service provider (ISP) appointed by. According to this: a) How many subnets can this business create within itself? b) The maximum number of hosts in each subnet (LAN) can you take? c) Let one of these subnets be given as follows: subnet 1 : 10000010.00110010.00000100.00000000 Does the computer with IP address 130.50.7.139 belong to this subnet? Show your work and reasoning for each option.
