Correct. - Bobby Mathew
I dont have a clue how you got that.
All 4 of are really similar, so if you can get the first one, then it'll be really easy. For the first one, the range is from 0-255, so there are a total of 256 numbers. To find out the number of bits, just find out what power of 2 gives 256. 2^8 = 256. Its 8 bits for each number, hence 32 bits (8x4) for the entire IP address.-Bobby Mathew
Are going to have to know all of the powers of 2 memorized? Because after a certain, point, it's hard to memorize. Like 2^11, 2^12, 2^13, 2^14, etc?
You mainly need to know 2^8 = 256, and 2^16 =65,536. - Bobby Mathew
