Find the network identifier and host identifier of each of the following classful IPaddresses:i. 130.30.13.10ii. 220.20.10.130

To find the network identifier and host identifier of each of the given classful IP addresses, we need to determine the class of the IP address based on the first octet.

i. For the IP address 130.30.13.10:

• The first octet is 130, which falls in the range of Class B addresses (128-191).
• Therefore, the network identifier is the first two octets (130.30) and the host identifier is the last two octets (13.10).

ii. For the IP address 220.20.10.130: - The first octet is 220, which falls in the range of Class C addresses (192-223). - Therefore, the network identifier is the first three octets (220.20.10) and the host identifier is the last octet (130).

So, the network identifier and host identifier for each of the given IP addresses are as follows: i. 130.30.13.10: Network Identifier - 130.30, Host Identifier - 13.10 ii. 220.20.10.130: Network Identifier - 220.20.10, Host Identifier - 130.
