In this article, we will discuss IPv4 and about the highest value, we can use for one byte. A byte is made up of eight binary digits (bits) that are all either 0 or 1. Let's see all this in the following article.

What is IPv4?
IPv4 stands for internet protocol version 4 which is the 4th version of the internet protocol. It is also called octet because each decimal number represents 8 bits or one byte.IPv4 takes the 4 bytes which are equal to 32 bits. It means we can use 4,294,967,296 (232) unique addresses. The IPv4 address is divided into two parts;
- Network address
- Host address
The network address determines how many of 32 bits are used for the network address and remaining bits are used for the host address.
Example:
129.144.56.50
The first underlined part represents the network address and the second part represents the host address.
The largest value for one byte:
One byte has a maximum value of 8 bits and the largest decimal which can be stored in one byte is 255. So, the largest value for one byte we can store is 255.
The largest value can be found as;
(2 ^ 8 -1) = 255
2 represents the base number and 8 represents the bits in one byte. Each bit has a value of 0 or 1 so new can represent 255 in binary like 11111111. Therefore 255.255.255.255 is the maximum range of IPv4 addresses. The address in this format is called the dotted-decimal form.
Conclusion
As a result, 2n - 1, where n is the number of bits, can be used to calculate the largest value. Hope it helped. Happy exploring!!
