(b) For example, Computer A can communicate with computer C by using TELNET. At the same time, computer A communicates with computer B by using the File Transfer Protocol (FTP). For these processes to receive data simultaneously, we need a method to label the different processes. Could you explain that method? (c) IP addresses can be given to devices statically or dynamically, Could you provide an example? Why IPv4 facing crisis? And how to get rid of these IP crisis

------please answer these (3) questions ------- 1) Consider this block 192.168.0.0/16 of private IP addresses to be used for a company LAN. Allocate IP addresses to the following departments: a. Dept1: needs to support 1000 users. b. Dept1: needs to support 250 users. c. Dept3: needs to support 64 users. 2) network admin wants to block all incoming and outgoing UDP flows and telnet connections. IP protocol field = 17 for UDP & telnet port# is 23. Fill in this ACL entry to configure the firewall. ( Fill ACL table with Action, soure dest# of Ip AND port#, and Falg bit)
42- An organization currently requires 40 hosts for its sales department. Given the IP Address 194.12.1.0 /24, design an optimal address scheme usingTradition Subnetting method, which will enable the connection of the sales department’s 40 hosts in one subnet and uses the remaining subnets for other departments’ hosts in the future. How many subnets have been created? Select one: A. 4 B. 6 C. 64 D. 16
Assume that a large number of consecutive IP addresses are available starting at 198.16.32.0 and suppose that two organizations, A, B, C, and D, request 1000, 3000, 2000, and 4500 addresses, respectively, in that order. For each of these, give the first possible IP address within the assigned subnet, the last possible IP address within the assigned subnet, and the subnet representation in slash notation (w.x.y.z/s). In the imagine I have the answers but I am very confused on how to get them. Specially after A and B I do not undertand how the initial address of C is 198.16.64.0 how did that 64 happen??? Please explain all in detail. Thank you!
