IPv6 structure

“

- [Instructor] IPv4 is 32 bits or two to the 32nd power. And that gives you roughly 4 billion IP addresses. But we ran out of those public IP addresses many years ago and now on the internet we use IPv6 for all new addresses. Two to the 128th power gives us roughly 80 trillion IP addresses per person and that should be enough for quite a while. When we calculate the value of IPv4 it's written in binary, which is one or zero on or off. And that has a relation to the gates that's in a processor, when power can come through one of those tiny little billions of gates then that means it's open and it's going to be a one, when it's closed it's a zero. That's how we ended up getting binary for IPv4, however, we've evolved from that. With IPv6 we now measure things in hexadecimal it's no longer on or off it's zero through nine and then A through F. A through F is the same as 10 through the number of 15, so zero through F is…
