> Performance? How exactly is ipv6 more performing? It even has bigger headers. IPv6 has smaller routing tables, doesn't required routers to recalculate header checksums and doesn't support packet fragmentation (the endpoints are required to handle that). This allows more efficient router designs despite the larger headers.
