Objectives: 1. Practice IP subnetting 2. Practice calculating address block size, first address, and last address Equipment and Software Tools Required: 1. none Introduction: Using classless addressing provides flexibility in using address blocks. Network administrator/designer can divide available address block into smaller blocks (sub-blocks). Those sub-blocks are used for different subnetworks. Therefore, every subnetwork will be given a sub- block that identifies the subnetwork and the hosts within it. Questions You have been asked by a small company to divide an address block over four departments (management, HR, accounting, and sales). Divide the given IP address block (check below) with minimal wastage of addresses. Check the following table for the number of addresses required for each department; determine the best subblocks for each department, then fill out the table's remaining fields. Required information about each subnetwork: 1. Subnetwork address 2. Mask 3. First IP address (use binary calculation) 4. Last IP address (use binary calculation) s. Address block size (use binary calculation) 6. Wasted addresses (block size - required addresses) The address block is 10.x.y.0/24, where x and y are the last four digits from your Student ID. Therefore, if your St. ID ends with 1740 then x=17 and y=40, and the address is 10.17.40.0/24. Note: - You have to solve by hand, scan, and submit (only handwriting answers will be considered) - Use the binary calculation method to find out the first and last addresses and the block size. Solve it by hand and show your entire calculations
