Understanding IPv4 and IPv6¶

Overview of Internet Protocol Versions¶

Internet Protocol (IP) serves as the fundamental framework for the Internet, facilitating data exchange between devices. The two main versions are IPv4 and IPv6. Here’s a breakdown:

IPv4: Introduced in the early 1980s, IPv4 uses 32-bit address space, allowing for over 4 billion unique addresses. However, with the exponential growth of internet-connected devices, this address space has nearly been exhausted.
IPv6: Developed to replace IPv4, IPv6 utilizes a 128-bit address space, resulting in a theoretical maximum of 340 undecillion addresses (3.4 x 10^38). This vastly expanded address space accommodates the serge of IoT devices and the global internet population.
