Teredo is an automatic mechanism for tunneling. It is based on 6in4 for obtaining better access to the IPv6 internet from a single node in an IPv4- only network. It also has Nat Traversal giving it the advantage of working even behind a NAT44 gateway. It’s vital to understand what is Teredo Tunneling Pseudo-Interface used for. It is a process of tunneling IPv6 traffic over an IPv4 network. Teredo is a transition technology.
IP stands for Internet Protocol, which is a communication protocol performing the task of identifying and locating the computers on networks and routing of traffic across the Internet. IPv4 addresses are 32-bit address allowing a maximum of over 4 billions different address. When there is the rapid growth of the Internet, it refers that there will not be enough free IPv4 addresses to allow new devices to connect.
In order to solve this problem of connectivity, a new protocol called IPv6 is developed. IPv6 address uses 128-bit address with a format of four hexadecimal digits that are separated by colons like fe80:: 12ac:fe44:192a:14cc). This allows many devices to get connected. During this period of transition from IPv4 to IPv6, a temporary method is used which called Teredo is tunneling.
What is Microsoft Teredo Tunneling Adapter?
Microsoft Teredo Tunneling Adapter is being used for repackaging the data packets and this also permits communication between IPv4 and IPv6 devices. The communication is made possible by the use of a 6to4 protocol for tunneling IPv6 data to a device with an IPv4 address. There is also Teredo tunneling pseudo adaptor driver in windows which is available on the net.
TheTeredo Tunneling Adapter server runs a publicly accessible IPv4 address. It forwards the IPv4 encapsulated IPv6 packet to the required destination. Teredo server allows its user to use “keep alive” traffic with the use of the server. This also keeps the NAT mapping between the client’s source port and the public IP address. This also allows a “refresh” interval that enables the user to verify if the source port is valid. The interval varies with the Teredo service. Source ports may change but Teredo server must have the knowledge to return back to its clients. Teredo keeps track for both the public IP address as well as the source port of the user.
When teredo tunneling occurs you may receive an error message indicating that “Teredo Tunneling Pseudo-Interface Code 10. This device cannot start Code 10”. On certain systems, you may also receive a bang next to Teredo Tunneling Device in the device manager. While you are trying to update this device for installation of the driver, your driver installation may not take place by leaving an error message. To fix this issue you need to perform the following steps:
Fix Using Command prompt
- With administrator credentials, you have to open a command prompt. To complete this action you need to find CMD and then have to right click on Run as Administrator.
- Now you have to type netsh and need to press Enter.
- Write “int teredo” and again press Enter.
