Complete the following steps to practice calculating a supernet: 1. Starting with the network ID 192.16.20.0/24, what is the default Class C subnet mask for this network? Write this information both in decimal and in binary. 2. How many additional network bits must be used for host information in order to have about 2000 hosts per supernet? Use the same formula you learned for calculating number of hosts on a subnet. Write the new supernet mask in binary and in decimal notation. 3. What is the CIDR notation for the network ID now
