Convert the following IPv4 address in presented in binary form, into dotted decimal form 10101100.01111011.00001101.10011101.

A. 172.123.13.157

B. 173.13.13.157

C. 172.122.13.15

D. 172.124.13.57








 

Suggested Answer: A



An IPv4 address in dotted decimal format is constructed using binary arithmetic. In binary arithmetic, each bit within a group represents a power of two.
Specifically, the first bit in a group represents 2 to the power of 0, the second bit represents 2 to the power of 1, the third bit represents 2 to the power of 2, and so on. Binary format is simple because each successive bit in a group is exactly twice the value of the previous bit.
The first octet is 128 + 32 + 8 + 4 = 172
The second octet 64 + 32 + 16 + 8 + 2 + 1 = 123
The third octet 8 + 4 + 1 = 13 -
The fourth octet is 128 + 16 + 8 + 4 + 1 = 157
