IP Addresses are 32-bit addresses. This means that it takes 32 binary digits to create a complete address. A format referred to as decimal dot notation has four parts (or octets) separated by a decimal. Each octet is a decimal number that can range from 0 through 255 which is the range that you can count to with 8 binary digits.

All number systems for expressing values have a base. The base determines how many unique digits or symbols make up the number system. The base-10 number system, also known as the decimal system, is the number system we are most familiar with and use in our everyday lives. It uses ten digits to represent all possible numbers. The base-2 number system, the binary system, uses only two digits: 0 and 1.
In the computer technology and data science world, the binary system is the number system of choice. Billions of tiny electronic switches make up the components of a computer system. These switches are either ON (1) or OFF (0). Use the red and green button to count up to 15 in decimal and back down in binary.
