To convert decimal to binary, first, subtract the decimal value to the MSB value of the octet and continue the process until you subtract to the LSB value or your result is already zero. Each 1’s should be an addend, and 0’s are disregarded. To do so, we will have to do a simple addition method of values based on the table above to get the corresponding decimal number. Now we take the number 168, for example, and convert it to a binary number. As stated above, there are 8 bits in 1 byte or can also be known as an Octet, and every bit corresponds to specific digits based on the most significant bit (MSB) and the least significant bit (LSB). The first method to do in converting decimal to binary numbers is to understand the corresponding decimal digits of the byte. Understanding the IP address given in the example above, below are the corresponding equivalent of decimal number to binary number. So since there are only two numerals that represent a binary digit, a usual example of it can be seen below.īelow is an example of an IPv4 address in decimal form and its corresponding binary format. The place holder in binary each has a value of, that is why Binary code is also known as the Base 2 Numbering System. Unlike the decimal number, a binary number system only has two numerals to binary representations, which are numbers 1 and 0. Once we get to the number ten, there is no numeral to represent this value, so we go one place value up from ones to tens and so on and so forth.īinary numbers are another number system that is mostly used to represent machine language. We use ten different numerals to represent the decimal numbers from zero to nine. Each 8-bit field, called an octet, represents a byte of the IPv4 address.Ī decimal is defined as a base 10 numbering system that most of us are very familiar with. Let it be remembered that IPv4 addresses are typically written in decimal digits, formatted as four 8-bit fields that are separated by periods. An IP address can be read both in binary number or decimal number but be aware that the network device only understands binary, so it is essential that we understand how to convert decimal to the binary system.
