Introduction
In this article, we will provide a comprehensive explanation of IP Address. An IP (Internet Protocol) Address is a unique number assigned to a device connected to a network. Each device, such as a mobile phone, computer, or laptop, has its own unique IP address.
IPv4 and IPv6
There are two versions of IP address: IPv4 and IPv6. IPv4, the most commonly used version, has a total length of 32 bits and is divided into four segments of 8 bits each. This version has a range from 0 to 255 and can generate a total of 4 billion unique IP addresses.
However, with the increasing number of devices connected to the internet, the need for more IP addresses arose. This led to the development of IPv6, which has a total length of 128 bits and is divided into eight segments of 16 bits each. IPv6 has a range from 0 to 65,535 and can generate a total of 340 undecillion (a number with 36 zeros) unique IP addresses.
Types of IP Addresses
There are two types of IP addresses: private and public.
Private IP Address: This type of IP address is used for personal purposes within a home or organization. It is used for data sharing and connecting personal devices. Private IP addresses are not accessible from the internet.
Public IP Address: Public IP addresses are used for businesses and websites that are accessible from the internet. These addresses are provided by Internet Service Providers (ISPs) and are necessary for worldwide network connections.
IP Address Classes
IP addresses are also divided into classes: A, B, C, D, and E. Each class has a different range of IP addresses.
Class A: The range of Class A IP addresses is from 0 to 126. The first number indicates the class, and if it falls within this range, it is considered a Class A IP address.
Class B: The range of Class B IP addresses is from 128 to 191. Similar to Class A, if the first number falls within this range, it is considered a Class B IP address.
Class C: The range of Class C IP addresses is from 192 to 223. Similarly, the first number determines if it is a Class C IP address.
Class D: Class D IP addresses are used for multicasting purposes and have a range from 224 to 239.
Class E: Class E IP addresses are reserved for research and development and have a range from 240 to 255.
