To make Teredo work, a special pseudo interface was created: the Teredo tunneling pseudo interface. This interface was like a virtual bridge between the IPv6 and IPv4 worlds. It allowed devices to send and receive IPv6 packets, even if they were connected to an IPv4 network.
The Teredo tunneling pseudo interface was assigned a special address, called a Teredo address. This address was used to identify the device on the IPv4 network and to route the encapsulated IPv6 packets to their destination. teredo tunneling pseudo interface
The core of the technology is a process called . Because many home routers and firewalls only understand IPv4, they may block modern IPv6 traffic. Teredo solves this by: To make Teredo work, a special pseudo interface
At the heart of Teredo's operation is the Teredo tunneling pseudo-interface. This virtual interface acts as a bridge between IPv4 and IPv6, making it possible for devices on an IPv4 network to communicate with devices on an IPv6 network without requiring a native IPv6 connection. The Teredo tunneling pseudo interface was assigned a
Teredo and its tunneling pseudo interface provided several benefits:
