The term "internet protocol IPv6" refers to the sixth version of the Internet Protocol (IP), which is essential for identifying devices on a network. IPv6 was developed to address the limitations of its predecessor, IPv4, particularly regarding the exhaustion of available addresses. It offers a vastly larger address space, providing unique identifiers for a significantly greater number of devices. Additionally, IPv6 enhances routing and network autoconfiguration, improving overall performance and security on the internet. As the world becomes increasingly connected, IPv6 ensures that the network can accommodate future growth.
