The answer for Windows and Microsoft devices is the Microsoft Teredo Tunneling Adapter. While some network addresses still use IPv4 and some use IPv6 and the two addresses look completely different, an adapter is needed to translate. Even without a degree in math, you can see that 10 38 is much, much larger than 2 32. IPv6 uses 128-bit addressing which gives us 3.402 × 10 38 addresses to choose from. As we have used most addresses we need another solution. While that sounds like a lot, we already have more than 4.2 billion connected devices and that number increases daily. There are 4.2 billion possible IPv4 addresses, which is 2 32 as it uses 32-bit addressing. We need more addresses to enable us to allow more devices online.
