The world in which IPv6 was a good design

IPv6 was designed to address the impending IPv4 address depletion, but in a world with vastly more devices and slower network speeds, its design may be seen as optimal. This perspective argues that IPv6's larger address space and improved routing efficiency are beneficial in a world with slower networks. As a result, IPv6 may be considered a good design choice. Engineers should consider the trade-offs between address space, routing efficiency, and network speed when designing networks.
