Most of us, are on the IPv4 technology and so is the rest of the world. However, due to all the IPv4 available addresses being occupied the Internet is running out of IPv4 addresses as more and more of us have started using internet and networks heavily which is the main reason we now have the IPv6 (Internet Protocol Version 6) which brings in an uncountable number of addresses, that is 2 to the power of 128 – 2^128 (340,282,366,920,938,000,000,000,000,000,000,000,000) never-ending. Now that you know about the shortage of IPv4 addresses – it’ll be easier to understand what the Teredo Tunneling is. IPv4 is still being heavily used, to put it in it’s simplest terms, I’d say that previously every one knew one language, but now there are two so the person (system) speaking in an IPv4 language will be understood by the same but not by those speaking in the IPv6 language, hence making networks talk to each other will not be possible and internet is all about networks connected and talking to each other – therefore, we need an interpreter to translate IPv4 to IPv6 and vice-versa and this is what the Teredo Tunneling is, it is an interpreter to process the v6/v4 language.
