Using packet tracer, implement a network that has the following components: 1- At least five routers 2- At least 7 subnets 3- At least 12 PCs 4- At least 4 switches 5- Use RIP routing protocol To assign IP addresses of the routers and PCs, use the IP address from your ID as follows Assume your id is 118zyxw, Consider the numbers z, y, x and w as deciemal You have the subnet 118.0.0.0/24 If your ID is 1181234 then the IP is 118.0.0.0/24 Use this subnet to get at least 7 subnets.
A network configuration of a modem is given as following:LTE interface IP = 77.110.156.22 MASK 255.255.252.0Default GATEWAY = 77.110.156.1Masquerade NAT, and DNS address = 1.1.1.1Local IP setup: 192.168.128.1 MASK 255.255.255.0And, ip route 192.168.128.0 255.255.252.0 192.168.128.254 Devices numbered R1, R2, R4, R5 are routers. PC is a computer.Image of network with interface names such as f1/0 are added. You must use only static IP addreses and static IP routes to configure the network and make PC able to connect (ping) to Modem.
Given, a network address of 161.0.0.0/10. Using the figure above and by applying VLSM technique, find the network address of the subnets A, B and C. Where Subnet A has 2788 hosts, Subnet B has 484 hosts and Subnet C is the switched network interconnecting the routers. Upload Picture Please
4. A router receives a packet with destination address 196.77.26.206 Show how it finds the network and the subnetwork address to route the packet. Assume the number of subnetworks required is four. Please solve it using the keyboard, not using the hand, and quickly, and I hope that the solution is correct.
A router with IP address 125.45.23.12 and Ethernet physical address 23:45:AB:4F:67:CD has received a packet for a host destination with IP address 125.11.78.10 and Ethernet phys-ical address AA:BB:A2:4F:67:CD. (I) Show the entries (a, b, c, d, e in Figure 1(a)) in the ARP request packet sent by therouter. Assume no subnetting. (II) The packet made in part (I) is encapsulated in a data link frame. Fill in the fields fand g in Figure 1(a). (III) Show the entries (h, i, j, k, l in Figure 1(b)) in the ARP reply packet sent in responseto part (I). (IV) The packet in part (III) is encapsulated in a data link frame. Fill in the fields m andn.
Suppose a user from Taman Jatt Kata Kinabalu is working from a machine at home with IP address 10. 0. 0.10 on a local network attached to a router connected to the Internet The user requests a web page through a Web browser. Show using illustration when and why each of the following aspects of networking are involved. Be as precise as possible. i ARP ii NAT iii DNS iv UDP v TCP.

Consider the following non-default subnet masks: (a) 255.255.248.0, (b) 255.128.0.0 . To which IP address class do they pertain?Write down the following in CIDR notation: (a) IP: 150.160.170.180, Subnet Mask:255.255.224.0; (b) IP: 75.80.85.90, Subnet Mask: 255.252.0.0 Three stations A, B, C and D are connected to a common Ethernet hub. Their IPaddresses and subnet mask are respectively: 200.100.50.67, 255.255.255.252;200.100.50.7, 255.255.255.248; 200.100.50.138, 255.255.255.240 and 200.100.50.1,255.255.255.254. Determine which among these stations can communicate with eachother. You need to show all detailed workings.
Choose a set of class C, /24 addresses that could be successfully combined into a supernet that supports 3000 hosts.
22. A datagram subnet allows routers to drop packets whenever they need to. The probability of a router discarding a packet is p. Consider the case of a source host connected to the source router, which is connected to the destination router, and then to the destination host. If either of the routers discards a packet, the source host eventually times out and tries again. If both host-router and router-router lines are counted as hops, what is the mean number of a. (a) hops a packet makes per transmission? b. (b) transmissions a packet makes? (c) hops required per received packet?
