Question

What is octet in IP address?
​

Answer 1

Answer:

The 32-bit IP address is grouped 8 bits at a time, each group of 8 bits is an octet. Each of the four octets are separated by a dot, and represented in decimal format, this is known as dotted decimal notation. Each bit in an octet has a binary weight (128, 64, 32, 16, 8, 4, 2, 1).

Answer 2

The IP address consists of 4 decimals – called octets – which are separated by points. One octet contains 8 bits, which is why IPv4 is a 32-bit address. Each octet can represent a number between 0 and 255. In this case, the whole of the last octet consists of host bits.
