2. Halaman Dhuha Sdn. Bhd. has been granted a block of addresses with the beginning address of 70.15.30.0/X. The company needs 128 addresses for its headquarters in Kuala Terengganu. In addition, the company allocates 64 addresses to its other branch in Johor Bahru, and 32 addresses for its other branch in Penang. Assuming that these offices are connected via point-to-point Wide Area Network (WAN): i) Determine the prefix for the site, headquarters, and the other two offices. ii) iii) Find the first and last addresses of all offices owned by this company. Suppose that the company decides to allocate fix subnet of 32 addresses for each office, find the number of addresses for the whole site.

1. Design the network as per the requirements below: The company is composed of 3 Branches, namely: Head Office (HO), Northem Governorate Branch (NGB) and Southern Govermorate Branch (SGB). Each branch is represented by a router. Utilize 1841 routers. These branches are separated by WAN links where the HO is connected to both branches. HO has 2 LANS and NGB and SGB have 1 LAN each. Use 2960 switches. Utilize any Class C address and assign the appropriate IP addresses for the interfaces and end devices. Place 5 hosts in each LAN. Label your network.

An ISP has the following block of addresses 132.204.192/20. The manager of this ISP hired you to help him assign IP block of addresses to the following subnets. Subnet A should have enough addresses to support at least 850 interfaces;  Subnet B should have enough addresses to support at least 55 interfaces;  Subnet C should have enough addresses to support at least 46 interfaces;  Subnet D should have enough addresses to support at least 40 interfaces; Subnet E should have enough addresses to support at least 20 interfaces.  Subnet F should have enough addresses to support at least 28 interfaces.  Give the range of addresses (in binary) assigned to each subnet. Show your work.

A regional ISP is granted the following block of addresses: 15.0.0.0/18. The regional ISP has decided to divide this block into 4 equal sub-blocks (0 to 3). Three of these sub-blocks are assigned to three local ISPs. The second block (block no. 1) in the group is reserved for future use. (i) How many addresses does each local ISP  get? (ii) What is the address of the block reserved for future use? Explain your answers!

Consider the ACME company which was assigned a public class B IPV4 network (137.151.0.0/16). The organization has currently 11 large branches in operation and plan to add 7 more within several years to bring the total to 18 branches. Each branch may have a maximum of 4000 devices except for 4 relatively smaller branches that can only sustain 2000 devices at most. The company must provide a separate network to support both current and future branch offices. Show how the ACME company's public network is divided using subnetting to satisfy both the short-term and long-term goals. You must show all your work and list all calculated subnets. • Requirements • Total subnets • Block size ( • Size per subnet ( : 18 subnets total, where 14 subnets must support up to 4000 hosts, while 4 subnets must support up to 2000 hosts. : 20, where bis the borrowed host bits on the 3rd octet ): 2", where r is the remaining host bits on the 3rd octet ): 2h, where h is the remaining host bits on the subnet…

Suppose that there are four sites as shown in the following figure. S1 2 Bytes 5 Bytes S2 S4 4 Bytes S3 A query at site 4 requires to transfer 2, 5 and 4 bytes from sites sl, s2 and s3 respectively. Assume that the time of initiating or receiving a message from a specific site is 0.2 seconds and the time of transferring one byte from one site to another is 0.4 seconds. Compute the total time and the response time for that query. (Assume that only the communication cost is considered)

Assume a company has three offices: Central, East, and West. The company is granted a block of 64 addresses with the beginning address 70.12.100.128/26. The management has decided to allocate 30 addresses for the Central office and divides the rest of addressesbetween the two other offices equally. Design the subnets. (Find: Mask, Network and Broadcast address, First and last address, number of usable addresses in each network).

A) Assume there is a wide-area network with N nodes, where N ≥ 2 What is the smallest number of point-to-point communication links such that every node in the network is able to talk to every other node? (Note: A network in which some nodes are unable to exchange messages with other nodes because there is no path between them is called disconnected.)

A Telecom operator has been assigned the bandwidth from 2100MHZ to 2105MHz, this can support 100 voice channels and 6 users per channel. Assume there is a guard band of 10KHz then what will be the size of a single channel? And how many total number of users could be accommodated? Draw figure on your note book along with your arid number(my arid num is 19-arid-1141) and then add screen shot here

The first thing needed is a IP-addressing range to use in our network. Since this assignment is done in a laboratory setting, we don't have to comply to the RFC1918[2] standards of private IP-addressing. An IP address is written in the form shown in equation (2.1.1). X grpl grp2 grp3 grp4 X grpl grp2 grp3 grp4 We need however to take into consideration that the address range of 224.0.0.0/3 have been reserved, for amongst other thing multicast. Because of this, we will need to use another modulus-value on the first octet when we are generating a usable ip-address range. Start by creating your groups unique IP-address range using equation (2.1.2) where {x,y EZ | 0≤x≤ 223,0 ≤ y ≤ 255} (2.1.2) where {x EZ | 0≤x≤ 255} Where each octet will be based on each group members birthday. Value X is calculated according to equation (2.1.3), and value Y is calculated according to equation (2.1.4). YY * MM + DD mod 223 YY MM + DD X mod 255 grpl (2.1.1) The fourth group in the IP-address should be set…
