What's The Difference Between IPv4 and IPv6?

Did you know that every internet-connected device has a unique IPv address? It’s true, up until recently, all internet-connected devices used what’s known as an IPv4 addressing scheme denoting a 32-bit address for internet and internet-connected device addressing. This 32-bit address provides 4.29 billion unique addresses that can be assigned to devices. One might think this is exhaustive and that we will never outgrow that number, but surprisingly, we already have.

As addressing schemes approached the 4.29 billion limit, device architecture moved to what's known as IPv6 addressing, or 128-bit addressing. Astonishingly, IPv6 addressing supports 340 trillion trillion trillion IP Addresses, 1028 times larger than the addresses available in IPv4 addressing. This incredibly large bay of addresses can support up to 1,500 addresses per square foot, covering the entire earth's surface!
