This mechanism is called tunneling. Basically, IPv6 packets are placed inside IPv4 packets, which are routed through the IPv4 routers. The following figure.
Tunneling provides a way to use an existing IPv4 routing infrastructure to carry IPv6 traffic.
Transition Concept. • IPv4 to IPv6 Transition and Co-existence. • Dual-Stack Configuration. • Dual-Stack Challenges. • Tunneling Concept.
Junos OS enables service providers to transition to IPv6 by using softwire encapsulation and decapsulation techniques. A softwire is a tunnel that is created.
IPv4 over IPv6 Overview You can create a tunnel on an IPv6 network to connect isolated IPv4 sites so that isolated IPv4 sites can access other IPv4.

A 6to4 tunnel interface automatically converts the 32 bits in its IPv6 address following this prefix to a global unicast IPv4 address for transport.
The current address space provided by IPv4, with only4, , , addresses. Nowadays IPv6 tunneling over IPv4 are widely used to form the global IPv6.
