What is IPv6? IPv6 is the newest 'upgrade' from IPv4, which is what identifies your IP address. Classic IPv4 IPs are easy to identify. The format will usually go something like 127.x.x.x. IPv6 however, formats your IP in 64k bit; x:x:x:x:x:x:x:x. Go to a website right now and find out what your IP is. If it is in IPv6 format, you are at great risk of being hacked and spied on on a personal, device-level form. IPv4 is effective in that the address are disposable. You can you whatever address, as used by proxies. There is very little information you can gather from a simple IPv4 address. However,
IPv6 is extremely dangerous in that the way it is formatted, gives people much more open access and information about you. USING AN IPV6 ADDRESS, PEOPLE CAN FIND OUT THE MODEL OF DEVICE YOU USE, THE EXACT LOCATION (LAT, LON), YOUR DEVICE SERIAL NUMBER, ECT. The use of IPv6 targets people on a device-level, whereas IPv4 was very broad and could have one address for a multitude of people.
The scary thing is that IPv6 has been normalized and hidden away in routers and ISP for years. You probably never were told what IP version your router would give. And through this, it is easy for anyone to find out anything about you, and gain access to devices such as home-used security cameras.
Not only is it just the format of the IP which can provide anyone with so much information, it is the fact that IPv6 DISABLES GLOBAL FIREWALLS FOR DEVICES CONNECTED. IPv4 was implemented with NAT, a firewall to protect anyone connected and using the router. IPv6, on the other hand, does not have a firewall whatsoever. In order to be safe while using IPv6, they depend on the individual devices having their own personal network firewall.

Sounds yabai, is there any precautious measure that could be done? Or something, are we powerless against these?

There are ways to disable IPv6 in a number of different devices. It depends on the operating system of the device. It's important to remember that this transition to IPv6 won't affect you if you know how to manipulate systems. The only devices which don't allow you to disable IPv6 are Apple devices. I cannot think of any other devices that do this. On systems using Android/Linux/GNU it's very easy to manipulate the system to completely disable to IPv6 and instead default to IPv4. In windows, I believe there are settings in your network options to disable IPv6 or at least force IPv4 to be default.
For my daily desktop, I use Manjaro Linux. To disable IPv6, I edited a few lines of the GRUB menu to disable IPv6 from the device level. This is the ultimate firewall in my eyes. If i have any knowledge of your device, I can most likely help you.
However, if you are using an Apple product, this is not possible. You are stuck with IPv6.

I knew it, those Apple products were up to no good!

Me is windows 10 user (yeah I know), any advice?

Additionally, you can always use VPNs. My preferred VPN is PIA -- Private Internet Access -- You can get it for 30$ for a yearly subscription and it works beautifully on PC as well as mobile.

Why are you spreading dumb stuff like this?
First of all, a IPv6 consists of 128 Bits not 64,
the first 64 Bits -> Prefix,
the second 64 Bits -> Interface Identifier.

It's true that the prefix gets calculated using your devices MAC-address, HOWEVER, there are mechanisms implemented that protect you from getting tracked like that called "Privavy Extensions".
Also, you cannot track a person's exact coordinates using IPv6, since that's not something IP versions affect AT ALL.
Both IPv4 and IPv6 give you and equally rough estimate from where you're from. Most of the time the IP location of your adress is bound to the next really big city in your area.

We already ran out of IPv4 addresses, so there's no running away from IPv6. They will come for certain and they are the future, especially when more and more IoT Devices will get their own IPs as well.
Please inform yourself before spreading such misinformation.
It gives me a headache as someone who has worked in the field a lot.

Hmm

>>6 I don't know what to think about this thread as a whole lmao. Since I don't know anything about this.

And what do you mean by disables global firewalls XD most systems these days can work with IPv6 and also have firewall XD and for the MAC address thing google has been adding a new feature to most of its devices that gives out a random mac address(which i think is dumb)

Newest is an interesting term seeing as it came out over 20 years ago. Online IPv4 addresses also officially ran out over 5 years ago. Ofc they're now on a first come first serve basis when they become available. So you must be talking about Internal IPv4. Crazy how we have routers to mask personal addresses. Which is why we can have computers with the exact same IP address (just like we can have houses with the same street name and number)
I usually would've ignored something stupid like this, but Reimu was the only one debunking your inherently flawed logic. Don't we just love how people love to use half truths to spread misinformation?

It's good that we're moving to IPv6. The limited number of addresses available with IPv4 causes a lot of problems in our modern digital world.
ISPs use dynamic IPv4 address for all of our personal devices to get around how few address are available. What this means is that your public IP will change regularly. This works by your router/modem receiving a data package from your ISP telling it what it's new IP address is. If your router misses these packages your internet can cut out unexpectedly. In contrast IPv6 can provide all our devices with a static IP address which is just much better

IPv6 is just a better standard to move to. The tech is pretty old as it was developed in the 90s. The primary reason it hasn't been used for this long is because ISPs hate spending money on updating/upgrading their servers for something that doesn't make them any more money (thanks capitalism!?!?!). Probs gonna be pretty common place within the next 10 years because the problems with ipv4 are just gonna keep getting worse. Let's just hope this doesn't take as painfully long as it's taking the C++ std library to include basic multi-threading structures like semaphores and barriers :( - (yes I know they aren't hard to implement at all, it's just that these really should be part of the std library)
