Want to test your network for IPv6 readiness? Go to http://areyou.v6ready.info/ .
Also see the countdown clock. With all of the devices we have, tablets, laptops, desktops, servers, routers, phones and other devices, there are only so many left (IPv4 addresses)…
There are two types of IP addresses. Public and Private. Private numbers are NATed. They allowed us to have IP addresses that were 10.x.x.x, or 172.16.x.x or 192.168.x.x. NAT allows us to have multiple computers in our home and our home router would have one public number supplied by our ISP. May sound complicated to the novice but actually is pretty easy if you could see it drawn out. For example our school has four IP addresses that are public (we have four lines coming in) but behind it has hundreds of nodes (computers, Access Points, Bridges, Printers and other devices.)

Very nice post. I’d add that you need to begin planning to have your public servers (web, email, DNS) reachable via IPv6. Talk to your ISP about getting IPv6 over your existing IPv4 service, plan how to add IPv6 addresses to your external servers, and make sure you review your security configuration for handling IPv6 traffic.
