IPv6
IPv6 is the protocol trapped in a labyrinth of backward compatibility, despite heralding an infinite address utopia as the next-generation savior. Its dance of countless hexadecimal fragments serves only as a flashy cloak that conceals the hell of configuration files. Engineers applaud the grand vision while writhing in the snare of dual-stack complexities. It is as if a promised future utopia were a mirror reflecting the bitter childbirth of deployment reality each day.
