Question 2

The IP address range goes from 0.0.0.0 to 255.255.255.255 and is known as the "four octets". Why are these 4 numbers called octets?

1 / 1 point

The inventor noted the similarity to the "octives" in piano music.

They form a total of 8 subranges.

The number 255 in decimal takes up 8 digits in binary.

This was the eighth version of the IP address range to be adopted by the Internet Standards Committee (and the first to gain widespread acceptance.)

Correct

Correct, it takes up 8 digits in binary.
