IPv4 has lasted as long as it has due to workarounds like NAT, efficient routing techniques, and massive early adoption. However, it is not a sustainable solution for the future. The exponential growth of the internet, the surge in connected devices (IoT), and the depletion of the address space make IPv6 a necessity. IPv6, with its much larger address space, better security features, and simplified routing, is designed to replace IPv4.
