<networking> A protocol for transitioning from IPv4 to IPv6. Networks may use 6to4 (or other transitioning protocols) until they support native dual-stack.
Because 6to4 is a form of tunnelling, it requires encapsulation by a protocol converter. This can cause performance problems due to increased latency and decreased MTU sizes, as described in RFC 6343.
