1. In a class A subnet, we know the IP address of one of the hosts and the subnet mask as given below: IP Address: 25.34.12.56 Subnet mask: 255.255.0.0 What is the first address (subnet address)? What is the last address? 2. In a class C subnet, we know the IP address of one of the hosts and the subnet mask as given below: IP Address: 202.44.82.16 Subnet mask: 255.255.255.192 What is the first address (subnet address)? What is the last address? 3. In a block of addresses, we know the IP address of one host is 25.34.12.56/16. What is the first address (network address) and the last address (limited broadcast address) in this block? 4. An organization is granted the block 16.0.0.0/8. The administrator wants to create 500 fixed-length subnets. a. Find the subnet mask. b. Find the number of addresses in each subnet. c. Find the first and the last address in the first subnet. d. Find the first and the last address in the last subnet (subnet 500). 5. In classless addressing, we know the number of addresses, first addresses and the last address in the block. Can we find the prefix length? If the answer is yes, show the process and give an example
