You are hired to design and manage a network of a company. The topology of thenetwork is shown above. The Internet Service Provider (ISP) provides the followinginformation to connect the corporate network to the Internet.The CIDR range given for the company: 124.34.52.0/21The address of the ISP router (also called "Gateway address"): 124.34.63.254Configure the network by giving CIDR blocks for each company subnetand IP addresses for each station and router knowing that:For Ethernet 1, we need 514 hosts to connect.For Ethernet 2 we need 50 hosts to connect.For Ethernet 3 we need 123 hosts to connect.For the Token Ring network we need 132 hosts to connect.You need to take into account the gateway addresses that need to be allocated foreach of the subnets. Assign IP addresses to hosts A, B, C and D and IP addresses tothe router gateway interfaces.

2. The following illustration shows a transmission from Host A to Host B using Network Address Translation (NAT). Host A is located inside a Local Area Network (LAN) with an IP address of 192.168.1.2. The LAN is connected to the Wide Area Network (WAN), i.e. the Internet, through a router R1 that conducts NAT. R1 has two interfaces with an internal LAN IP address (192.168.1.1) and and external WAN IP address (127.45.10.35). Host B is located outside the LAN and is a well-known server, e.g., Google's server. Host B has an IP address of 130.160.23.45. Port numbers for the application components running at both hosts are provided in the figure. For a single message M1 being sent from Host A to Host B, please fill in the blanks in the illustration below with the source IP address and Port number at Host A and at the Router R1. Any information not provided may be assumed, however, please state your assumption clearly. Host A Local Area Network (LAN) IP: 192.168.1.2 Port: 5252 Source IP…
An Internet Service Provider (ISP) is granted a block of addresses starting with 150.80.0.0/22. The ISP needs to have 4 subblocks of addresses to use in its four subnets: one subblock of 200 addresses, one subblock of 330 addresses, one subblock of 100 addresses, and one subblock of 62 addresses. With the available information, a) Calculate the number of addresses in the block and determine the address mask, first address, and last address of the block. b) Determine the number of allocated addresses, subnet mask (n), address mask, first address, and last address for each of the subblocks. c) Calculate the number of unused addresses and provide its first address and last address. d) Illustrate the original block and the subblocks using two figures. The figures must contain the number of addresses, mask, first address, and last address.
