4g Mifi can cause Amazon account link through IPv6?

I read this from balsero on the marketplace forum:

Are all 4g data cards leaking IPv6 to Amazon? How do we protect against this? Or how can we check if our mifi device or data service provider (I use sprint) is safe?

I think he got the wrong end of the stick. I think what he read somewhere was ATT/Comcast are now compatible with IPv6 etc etc etc. and he misinterpreted that to be they are now using it.

His previous points are also incorrect, 3G data doesn't always give you a different IP each time, let alone a 'fresh' IP - so he's used the term incorrectly.

I would just dismiss what that user had to say and move on.

Yes, agreed, seems as this is some unfounded information. IPV6 has been being implemented for years. Most of the time its pretty seamless as IPV6 has an ability for auto-configuration not fully developed by IPV4. Much of the roaming data on cell phones and similar plans use IPV6. Anyway, this could be a never-ending topic, but the roots of it are that IPV6 isn't a real concern of stealth at this time that i know of. Disclaimer follows::There are always new concerns and problems that change on a regular basis when it comes to stealth. It is always wise to read and evaluate new info as it comes along and plan accounts accordingly.
