Solved in 3 steps
- 5 Internet Protocol version 4 (IPv4) was deployed on 1 January 1983. The addressformat in IPv4 is a 32-bit numeric value often expressed with four octets from theinterval [0, 255] separated by periods. At the time of writing this book, InternetProtocol version 6 (IPv6), with 128 bit-wide addresses, is slowly replacing IPv4. Intheory, how many IP addresses can be assigned in IPv4 and IPv6?• 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 BitsConsider an IP datagram with the following characteristics: Length of IP header: 20 bytes Total length of IP datagram: 1000 bytes DF flag 0 MF flag 0 Fragment offset 0 Suppose this datagram must be transmitted on a network where the (a) Explain why this IP datagram must be fragmented. How many fragments will be created? (b) After the fragmentation is performed, provide the value of the following fields for each of the fragments: (12 M) -Total length (in bytes) - Value of DF flag - Value of MF flag - Value of Fragment offset (as a decimal number) (c) What does a router do, if the value of the DF flag of an IP datagram is set to one?

- Consider an employee using their computer to send and retrieve email at their workplace. Only Ethernet networks are used for physical connectivity, but the mail server is located on a separate network. The employee’s network and the mail server’s network are connected by a single router which also has a connection to the Internet via the workplace’s ISP. Explain how the employees email client sends and receives emails using the email server, indicating any protocols involved and where any encapsulation/decapsulation occurs as data travels between the client, local mail server, and remote mail servers.Computer Science Suppose KDC X serves one community of users and KDC Y serves a different community of users. KDC X and KDC Y have an established shared symmetric key KXY. Develop the steps of communication needed to enable customer A of KDC X community, to obtain a shared session key with customer B of KDC Y community. KDC X shares a symmetric key with A, KAX, and KDC Y shares a symmetric key with B, KBY. At the end of the steps of communication A and B will have established a session key, KAB.4. The original HTTP protocol used TCP/IP as the underlying protocol. For each page, graphic, or applet, a separate TCP connection was constructed, used, and terminated. This caused several problems: one referred to as the elephant and mice problem and two aspects of connection overhead. Describe both problems. Why were separate connections used? Would UDP rather than TCP be a good alternative? What solution would you propose to these problems to improve HTTP performance?
- A denial-of-service (DoS) attack against the FTP server 192.168.56.1 has been reported. Prior to the FTP service being taken down, there were significant increases in FTP traffic. This link will provide to you a network packet capture that has been captured.Is it possible to identify the IoCs of this case from the viewpoint of an investigator?Synthesize the appropriate filters that may be utilized to finish your research and answer the following questions by using the packet capture analysis technique. What was the source of the sudden increase in FTP traffic?What happened in the hours and minutes before the FTP site was taken offline?Any files were transmitted to or from the FTP server, and were any user accounts compromised as a result of this?Q1/ Suppose you has IP address 220.254.255.x / 28, conclude the class and analyze the subnetting for finding mask address, number of subnets, addersses range of subnets , and number of hosts at each subnet. Q2/ How can perform encapsulation process of OSI model for sender, and what happen of encapsulation data at receiver side, explain and draw graph of that. Q3/ Discuss the advantages and disadvantages of shielding the copper cables .Q2.Part A: Suppose COMPUTER-A send a message “I will work hard in Finals” on internet to COMPUTER-B. How that communication takes place according to OSI 7 layers model? Write very short description of each of 7 layers DIAGRAM for your answers on both computers. Part B: Mentioned differences and similarities between term “TCP/IP” and “OSI Model” in your own words?
- Primitives of transport service assume asymmetry between the two end points during connection establishment, one end (server) executes LISTEN while the other end (client) executes CONNECT. However, in peer to peer applications such file sharing systems, e.g. BitTorrent, all end points are peers. There is no server or client functionality. How can transport service primitives may be used to build such peer to peer applications?If we have the network-ID of subnet 127.91.220.100 And as shown in the picture we need to plan network , Rt-A = 2100 hosts , Rt-B= 1000 hosts, Rt-C= 300 hosts, Rt-D = 600 hosts. NOTE: It is possible to allocate more than one subnet per interface. Create a table for each of the eight networks that contains the network-ID and subnet mask for the subnet/subnets in that network.Consider the IPv6 address 2001:DB8:5432:: /48 for the B&IT service provider. B&IT has 13 clients of which Strathmore University (SU) is the 5th client. Carry out the necessary subnetting exercise and assign the said subnets to all clients and highlight that which belongs to SU (Show your working) 2001:DB8:5432:: /48
