Correct Answer

192.168.1.100
1 1 0 0 0 0 0 0
128 64 32 16 8 4 2 1
So if we take 192 and subtract the largest number which is 128 it will leave you with 64 so a 1 goes over the 128 spot.
Taking the remainder 64 and subtracting the largest number possible which is 64 your left with zero. So a 1 goes over 64 and zero's over all the remaining numbers.Rate this question:
