Question:
In a Class B subnet, we know the IP address of one host and the mask as given below: IP address = 125.134.112.66 Mask = 255.255.224.0 What is the first address (Network address)?
In a Class B subnet, we know the IP address of one host and the mask as given below: IP address = 125.134.112.66 Mask = 255.255.224.0 What is the first address (Network address)?
Show Hint
To find the network address, always perform a bitwise AND operation between the IP address and the subnet mask.

The Correct Option is B
Solution and Explanation
To calculate the network address, perform a bitwise AND operation between the IP address and the subnet mask. IP Address: 125.134.112.66 (in binary: 01111101.10000110.01110000.01000010) Subnet Mask: 255.255.224.0 (in binary: 11111111.11111111.11100000.00000000) Performing bitwise AND operation: 01111101.10000110.01110000.01000010 & 11111111.11111111.11100000.00000000 = 01111101.10000110 Convert the result back to decimal: 125.134.112.0 Thus, the network address is 125.134.112.0.
