Each octet is same as 1 Byte in size and its of 8 bits. The minimum value of a octet is 0000000 in binary which value in decimal is 0 and the maximum is 11111111 which is 255 in Decimal. IPv4 is available in 2 notations or formats. 1st one is Binary Notation and its understable by the machine only. 2nd one is Dotted Decimal notation which is understandable by human.
