10 Things You Should Know about IPv6
I just read the WordPress article about World IPv6 Day, and many of the comments in response expressed that they only had a very basic understanding of what an IPv6 Internet address actually is. To better explain this issue, we have provided a 10-point FAQ that should help clarify in simple terms and analogies the ramifications of transitioning to IPv6.
To start, here’s an overview of some of the basics:
Why are we going to IPv6?
Every device connected to the Internet requires an IP address. The current system, put in place back in 1977, is called IPv4 and was designed for 4 billion addresses. At the time, the Internet was an experiment and there was no central planning for anything like the commercial Internet we are experiencing today. The official reason we need IPv6 is that we have run out of IPv4 addresses (more on this later).
Where does my IP address come from?
A consumer with an account through their provider gets their IP address from their ISP (such as Comcast). When your provider installed your Internet, they most likely put a little box in your house called a router. When powered up, this router sends a signal to your provider asking for an IP address. Your provider has large blocks of IP addresses that were allocated to them most likely by IANI.
If there are 4 billion IPv4 addresses, isn’t that enough for the world right now?
It should be considering the world population is about 6 billion. We can assume for now that private access to the Internet is a luxury of the economic middle class and above. Generally you need one Internet address per household and only one per business, so it would seem that perhaps 2 billion would be plenty of addresses at the moment to meet the current need.
So, if this is the case, why can’t we live with 4 billion IP addresses for now?
