What is Teredo Tunneling?
Before we get down to the business, you might want to know what exactly Teredo Tunneling is (If you have already known this, please skip this part). To know what we are dealing with, first you need to know IPv4 and IPv6.
IPv4 isan IP protocol (with the format similar to 192.168.10.25) which assigns our computers with a unique address which is our identity to communicate with the world on the Internet. Most of us are on the IPv4 technology.
As there are more and more netizens and less and less available IPv4 addresses, IPv6 (with the format similar to 2001:DB8:0:0:8:0:417A) which brings in an uncountable number of addresses, is introduced.
When every computer is only using IPv4 as a way of communication, they understand each other perfectly, so the network connection runs smoothly. But with IPv6 added in, they find it impossible to talk to each other and thus the network connection is a problem. Therefore, Teredo Tunneling works as a translator that translates IPv4 to IPv6 and vice-versa so the communication over Internet is possible again.
