“Huh?” you might be asking yourself…but think about it. How many times have you looked at an application’s “Preferences” or “Options” window and seen a screen like this:
How well will that work with an IPv6 address?
In fact, as I was first writing this book, I happened to notice that the game Minecraft had a new release. One of the many changes was related to the format of the IPv6 address being entered into the app:
