-This is the most commonly-used Service Type. It provides native IPv6 connectivity to your network.

-6to4 is a transition protocol for migrating from IPv4 to IPv6.  6to4 acts as a transparent transport layer between IPv6 nodes. It allows IPv6 packets to be transmitted over an IPv4 network, such as the Internet, without requiring you to configure explicit tunnels. 6to4 hosts and networks communicate with native IPv6 networks via Special relay servers, known as "6to4 Anycast Relays".+6to4 is a transitional protocol for migrating from IPv4 to IPv6.  6to4 acts as a transparent transport layer between IPv6 nodes.
