    one cent from my search:



    Automatic
    6to4 Tunnels

    IPv4-compatible tunnel

    point-to-multipoint tunnel

     

    point-to-point tunnel

    routers are not configured in
    pairs

     

    IPv4 address embedded in the IPv6
    address is used to find the other end of the automatic tunnel

     

    may be configured on a border
    router in an isolated IPv6 network

    can be configured between
    border-routers or between a border-router and a host

    creates a tunnel on a per-packet
    basis

     

    tunnel destination is determined
    by the IPv4 address of the border router

    tunnel destination is
    automatically determined by the IPv4 address

     

    use IPv4-compatible IPv6 addresses

     

    easy method to create tunnels for
    IPv6 over IPv4

     

    Technique does not scale for large
    networks.

    ashse,

     

    It is easy.

    Suppose you were in a spa.

     

    v4 = man

    v6 = woman

    IPv4 compatible address = mixed bathing

    6to4 = woman with male costume
