IP Addressing and Subnetting
Exercise
1. Write the default subnet Masks for the Class A, Class B and Class C IP addresses.
2. How we can distinguish Class A, Class B, Class C, Class D and Class E IP addresses from each other. Write the range of first octet in binary and decimal for all the 5 IP address classes
3. Write the default subnet Masks for the following IP addresses: a. 100.100.225.100 b. 200.0.0.2 c. 190.47.115.0 d. 192.11.39.2 e. 101.7.80.0
4. Write down the three available ranges for assigning Private IP addresses recommended by IANA (Internet Assigned Number Authority).
5. What do we mean by Loopback address. Write down a Loopback address and its use.
6. What is the difference between a broadcast address and Network address? Why the all zeros and all ones addresses are usually not assigned as host IP addresses?
7. A mask is used to distinguish how many bits are there in Network ID portion and how many are in host ID portion. We can extract the Network Address from the given IP address using the mask. (Assume that no subnetting is done). Extract the network address from the following IP addresses: a. 139.65.225.4 b. 201.35.20.18 c. 190.47.115.6 d. 192.11.39.2 e. 10.7.80.0
8. A broadcast address is the one that addresses to all the hosts in any network. State that to create a broadcast address, all the bits of network ID portion, or all the bits of host ID portion are set to 1? Write down the broadcast addresses of the networks to which the following IP addresses belong. (No subnetting) a. 139.65.225.4 b. 201.35.20.18 c. 190.47.115.6 d. 192.11.39.2 e. 10.7.80.0 Note: First of all find network address of each address then find broadcast of that network.
9. In subnetting, we actually borrow some bits of Host ID to be used as Subnet ID. Each
