“IPv6” refers to the Internet Protocol version 6, which is the most recent version of the Internet Protocol designed to replace IPv4. It provides a vastly larger address space, enabling a more extensive number of devices to connect to the internet. IPv6 addresses are composed of eight groups of hexadecimal numbers, which allows for trillions of unique combinations. This upgrade is essential for accommodating the growing number of devices and ensuring seamless internet connectivity in an increasingly digital world.
