A couple of things to note:<p>+ I use a laptop for work, some video streaming and very light online gaming.<p>+ My ISP might or might not support IPv6, but let's assume it does.
Absolutely nothing.<p>+ You're in the majority. For example, only ~40% of the global traffic Google receives is over IPv6.<p>+ There aren't any generally availably internet services.<p>If you ever find yourself worrying about NATs, reverse NATs, or, generally, exposing things running with a non-internet facing IP addresses to the Internet, it may be time to learn more about IPv6.<p>Until then, for the use-case you've described, you're good.
