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)?

Question

Consider the transmission of data bits 110001011 over a link that uses Cyclic Redundancy Check (CRC) code for error detection. If the generator bit pattern is given to be 1001, which one of the following options shows the remainder bit pattern appended to the data bits before transmission?

Answer 1

The network address is determined by performing a bitwise AND operation on the IP address 125.134.112.66 (binary: 01111101.10000110.01110000.01000010) and the subnet mask 255.255.224.0 (binary: 11111111.11111111.11100000.00000000). The bitwise AND calculation is as follows: 01111101.10000110.01110000.01000010 & 11111111.11111111.11100000.00000000 = 01111101.10000110. This binary result converts to 125.134.112.0 in decimal, establishing 125.134.112.0 as the 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)?
