I have IPv4, the rest is just junk, which can cause problems, required only if you use sharing or something like that.
As for IPv6, I am behind 5 routers, ISP does not plan to use it anytime soon, but I am glad, it is a privacy nightmare.

I am not sure my system uses all of the Protocols listed , some are added by the Realtek Drivers and some by Windows , but I don't know enough to know what I could remove. I do use an internal network for the house, so I also use Client for Microsoft Networks and the File and Printer Sharing and I think the Link Layer stuff is for that too. Most of the Protocols I see on the Realtek Nic are the Same as on my Intel Nic on another computer so I assumed most were installed by Win10 for some reason?

I just got IPV6 recently , so am interested to know more about why it is a Security/Privacy Nightmare ?

Why the FBI wants IPv6: Because IPv4 with NAT makes it hard to track criminals -- GCN

Then again, it seems, that I was using an outdated information, I have just always disabled IPv6 as a custom. But since my ISP stated, he does not even plan to implement IPv6, he can use many NAT routers as he wants, it does not matter.

IPv6 stateless configuration uses the hardware device unique MAC address to create the IP last 64 bits, this means that your computer MAC address is exposed to the Internet, since any website you visit logs your IP they can also figure out your physical network card MAC address. IPv6 has something called Privacy Extensions (RFC 4941), enabled by default in Windows (not enabled in Linux and Mac OS X before Lion), it uses a random number generated by a computer algorithm to dynamically assign a varying address block when creating the IPv6 address so that your computer MAC address is not used and remains hidden.

If you see the characters “ff:fe” in the middle of your IPv6 address then your network card MAC address has been used to create it, if the characters are not there, privacy extensions is enabled and you do not need to worry.

Thanks for that , I will have to look into it, even the techs at my ISP seem like they really aren't aware of it ,or its implications.
