IPv4 and IPv6 are Internet Protocol (IP) versions used to identify devices on a network and enable them to communicate with each other.
IPv4 is the fourth version of the IPV(Internet Protocol version), the primary protocol to transmit data across the internet. It uses a 32-bit address space, allowing approximately 4.3 billion unique addresses. IPv4 has been the primary protocol used on the internet since its development in the 1980s, but as the internet has grown, the number of available IPv4 addresses has become increasingly limited.
IPv6 is the sixth version of the IPV(Internet Protocol version), which was developed to address the limitations of IPv4. It uses a 128-bit address space, which allows for a virtually unlimited number of unique addresses. IPv6 also includes additional features and improvements over IPv4, such as improved security and support for real-time communication.
The main difference between IPv4 and IPv6 is the size of their address spaces. While IPv4 has a 32-bit address space, IPv6 has a 128-bit address space, which means it can support many more devices. Another difference is the structure of the addresses themselves. IPv4 addresses are written in a dotted-decimal notation, while IPv6 addresses are written in hexadecimal.
In summary, IPv4 is the older and more widely used protocol but has a limited number of available addresses. IPv6 was developed to address this limitation and includes additional features and improvements over IPv4.
