It's fine if it's your public IP but it can cause some really stupid issues if you're using it for your internal devices. Windows doesn't handle them too well, I had to turn it off for several companies because RDP and sometimes dns just stopped working out of nowhere
When using a VPN ipv6 will leak. If you're a nomad or on a public wifi you may not be able to disable it on the router. I can disable in ubuntu easily but in android there is no option unfortunately. Still searching...
That's a problem with your VPN provider. Switch to one that offers IPv6 or has a leak protection, the prior is always better though. It's also good that it's not possible to disable it on Android/iOS, prevents people from blindly doing that, hindering adoption. Just don't blindly disable it. Talk to your VPN provider/ISP if issues arise.
With ipv6 you have public ip. And you can share/host things publicly, for example: a media server, share files, game server that supports IPv6, like Minecraft and other things.
Just don't disable it. If there is a problem: talk to your ISP. If it is with a VPN: switch to a provider that gives you IPv6 or has leak protection. The privacy concerns were solved using "temporary addressing" and "stateful firewalling" (the thing people associate with NAT being "secure" per-se). Never blindly disable IPv6.
@@CaptainBones222 Nothing really good happens, only bad things, like you'll be able to access less websites now and especially in the future, microsoft windows features also rely on it, aswell as stuff like apple airdrop. IPv6 is rarely the problem, it's usually drivers or ISP.
Not really. Most of the privacy fears that get recycled are old information from before privacy extensions became the default, meaning your IPv6 as seen by external sites and ISPs are temporary and will change frequently and no longer be correlated to your device's MAC address. They will still have your network prefix, but that limits them to equivalence of knowing your router's public IP rather than any specific actual client user device. So you're far more liable to pre-existing tracking code used by websites profiling your browser and/or storing something on your device than by your temporary IP address. As regards VPN / DNS leaks / ISP - well * your router does not need to use your ISP's own DNS servers * make sure your VPN provider is fully dual-stack including providing DNS, so that you have control and the choice over when/if to use it or not from the client side settings * check what traffic you are routing over the VPN (a VPN client usually modifies your routing table on connect) * decide what use cases make the most sense for when at home/office versus out and about (because these are different scenarios and risk factors of merely masking your activity or trying to securely reach something at the other end of the tunnel) The remaining problems will be things like a rubbish ISP providing a mis-configured router rather than inherent to the protocol, rather than from one that decisively either does it correctly or not at all.
Not really, but most people don't know ipv6 and leave the dns to auto. This uses the ISPs DNS and it makes for some really bad times. That was the context for what I was talking about in the video. Knowing and properly configuring ipv6 is recommended. However, most people still only know ipv4... It's like another wayland vs xorg type thing.

@@katrinabryce It has benefits, it will improve the network topology, thereby improving performance. You can host things publicly, like minecraft, an sftp server (files). lower latency. And with more people using IPv6, more things will support IPv6. And this is very good, for games and things that require a direct connection such as games, video conferencing, etc. latency and voice chat issues and other problems happen because of nat/cgnat, increasing the cost and complexity of the network. With IPv6 these problems do not happen. ipv4 with nat/cgnat is more expensive than ipv6 and they have to keep the 2 together, ipv4 and ipv6. So if it only had IPv6, it might even make the price of an internet plan cheaper.
It does not increase the attack surface. Pretty much all consumer routers have something called "stateful firewalling". It's what makes stateful NAT work. Simply keeping track of the connections. It is useful, especially if you want to host servers or use the modern version of the internet. IPv4 is just broken and the switch is inevitable. Just leave it on and do it's thing, if any problems arise => consult your ISP.
