1 Consider the NAT scenario below. IP datagrams being sent from, or destined to, these three private hosts must pass through the NAT router. Suppose that the host with IP address 192.168.0.3 sends an IP datagram to a host on the Internet with 170.109.109.77. Show the Source (S) and the Destination (D) IPs in steps 2 and 4 only.

Please help with the following: Consider the network address 199.200.30.0. We want at least two subnets and between 60 and 70 hosts per subnet. What subnet mask should we use? What would the numbers of the first 2 and last 2 subnets be, along with their address range and their broadcast? Explain your answer.

44. [Theoretical] A student has configured a software router and two workstations on a private LAN. He has set up the network with IP address 10.0.0.0 with subnetting that borrows bits 15, 16 and 17 (ONLY bits 15, 16 and 17, counting from the left) to create eight subnets (six useable). The student has configured one workstation on the second useable subnet as the lowest available host IP address. The router has the highest usable address on this subnet for its interface connection to this network. The student has set up the other workstation using the 138th useable IP address on this subnet. a. What are these three IP addresses in binary? b. What are these addresses in dotted decimal?
If the IP address is 192.168.1.5 , the mask is 255.255.255.240,(1) convert the P address and mask in binary format, (2) give the class of the network, the number of bits for subnet, and the number of bits for hosts, (3) the (network id)/(\# of mask bit) in decimal format, (4) subnet broadcast address in decimal format, and (5) the range of valid hosts addresses in decimal format.
Consider the subnet address 100.0.0.0, divided into 9 subnets. If we want to maximize the number of hosts per subnet, what subnet mask should we use? What would the numbers of the first 2 and last 2 subnets be, along with their address range and their broadcast? Explain your answers.

Consider 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?

Suppose a router has built up the routing table shown in Table 3.19. The router can deliver packets directly over interfaces 0 and 1, or it can forward packets to routers R2, R3, or R4. Assume the router does the longest prefix match. Describe what the router does with a packet addressed to each of the following destinations: (a) 128.96.171.92 (b) 128.96.167.151 (c) 128.96.163.151 (d) 128.96.169.192 (e) 128.96.165.121 Table 3.19 Routing Table for Exercise 56 SubnetNumber 128.96.170.0 128.96.168.0 128.96.166.0 128.96.164.0 (default) SubnetMask 255.255.254.0 255.255.254.0 255.255.254.0 255.255.252.0 NextHop Interface 0 Interface 1 R2 R3 R4
sWin an international IT solutions company, is launching 11 new branches in a new country where they currently have no existing branches. The sWin CIO has asked that each subnet should host at least 2000 devices. sWin has obtained a network address of 10.11.0.0/17.This address needs to be subnetted further and the CIO has decided that the internal subnet mask will be /21 The company’s subnet plan allows for: Router Pool: 2 router interfaces for each subnet – the last 2 IP addresses from each subnet. Managed Network Device Pool: The first 64 IP addresses are reserved for switches and other network devices Server Pool: The first 64 IP addresses following the Managed Network Device Pool are reserved for servers. Workstation Static Pool: The first 16 IP addresses following the Server Pool are reserved for Workstations that require static IP addresses. Workstation DHCP Pool: The remaining IP addresses are reserved for automatic IP configuration. You have been asked to use subnet 10 for…
