The term that describes the process of encapsulating IPv6 packets inside IPv4 packets is tunneling.
Tunneling is a mechanism that allows for the transfer of one network protocol over another network protocol. In the case of IPv6 over IPv4 tunneling, the IPv6 packets are encapsulated inside IPv4 packets and then sent over an IPv4 network.
Tunneling is necessary in situations where there are incompatible network protocols, such as when an organization wants to use IPv6 but its network infrastructure only supports IPv4. By encapsulating IPv6 packets inside IPv4 packets, the organization can transmit IPv6 traffic over an IPv4 network.
There are different types of tunneling mechanisms that can be used, such as automatic 6to4 tunneling, configured tunneling, and tunnel brokers. Automatic 6to4 tunneling is a mechanism that allows for automatic creation of IPv6-in-IPv4 tunnels between IPv6-enabled hosts across the IPv4 network. Configured tunneling requires manual configuration of the tunnel endpoints. Tunnel brokers are third-party services that provide IPv6 connectivity to organizations by establishing tunnels between the organization's network and the broker's network.
In summary, tunneling is the process of encapsulating one network protocol inside another network protocol. In the case of IPv6 over IPv4 tunneling, IPv6 packets are encapsulated inside IPv4 packets, allowing for the transfer of IPv6 traffic over an IPv4 network.
