Well… only about 10 years after headlines were fearmongering about the world breaking due to IP addresses not being available.

The “breakage” is happening. It’s just in the form of crappy solutions like CGNAT and DS-lite to work around the shortage rather than the internet just not working at all.

Earlier quoted context omitted.

Having a non-residential IP address is likely to get you blocked from services like Netflix. It would be nice if there were some way to decouple connectivity from addressing, without becoming a second-class citizen of the internet.

I don't use Netflix but that never happened to me.

I'd go so far as to say that it's actually never happened to anyone that doesn't use Netflix.

Anyone go out of their way to disable IPV6 on all their systems, even at the hardware level, like on routers etc? What's a good reason to avoid IPV6?

Not a residential user, but I ran a small p2p gateway for a few hundred users, and I ended up having to disable ipv6 resolution for remote servers because so many servers would just advertise an AAAA address that didn't work, so we got tons of timeouts. I would say this affected maybe 10% of servers. A lot of them seemed to be hosted on Hetzner, but I never got a good sense of the root cause—mostly seemed to be lack of testing or usage, like users who had typoed an ipv6 address or moved their servers and updated their A record without remembering to update their AAAA.

I sure wish Starlink supported IPv6. They're a brand new ISP planning for millions of customers and decided from the start they couldn't get enough IPv4 addresses for everyone. Fair enough! But we're stuck with Carrier Grade NAT and it is a drag. On Starlink it's impossible to host a server socket directly, which makes any peer to peer networking a PITA. Geocoding IP addresses doesn't work so I have to bend over back…

>I fill out 10x as many CAPTCHAs This a feature, not a bug. You can now identify a traffic light on a subconscious level 3x further away than the average driver that has an assigned IPv4. Where average drivers hesitate upon seeing a yellow light, wondering if they have enough time to go or not, you just know that a slight uptick in speed will get you through the intersection right as that yellow flashes over to red.

That’s a non-sequitur argument. Simply because your parent comment can identify the state of lights faster does not make them any faster at deciding whether to cross them because it doesn’t influence them to make different decisions based on the speed of their vehicle and then distance from the light.

Yes. Actually no, not disable, I use Local-Local, there's a rare application here and there that needs to see an IPv6 stack is available then connects normally over IPv4. Google and anyone touting IPv6 can take IPv6 and have a nice day.

>IPv4 servers are reachable by IPv6-only clients How does this work?

I forget this part of IPv6 class (I've literally gone to several IPv6 classes throughout the years but then end up forgetting details because I've yet to use it in production), but since the IPv6 space is so large, it's trivial to put an IPv4 address into it, and so they make NAT 6to4 type gateways that map the IPv4 internet into a block on the IPv6 network.

This wikipedia entry is a pretty handy reference: https://en.wikipedia.org/wiki/IPv6_transition_mechanism

None of the computers I own personally use IPv6. IPv6 is a bad idea. IPv6 is a straight connection from the Internet through everything in the network, right to the individual machine. Give my IPv4 and NAT or turn the Internet off.

I know it's been repeated a million times by now, but NAT is not a replacement for a firewall. Most residential routers are deny in by default so you get zero incoming connections from the internet unless you open the relevant ports, exactly as with NAT.

I've disabled it on my router. My reasoning is that I don't know what kind of firewall rules, if any, the router has for ipv6 traffic. If it's just going to forward any valid incoming ipv6 dst address, that would seem like a new risk. I'm happy to be convinced otherwise by knowledgeable folks.

>IPv6 is a straight connection from the Internet through everything in the network, right to the individual machine.

It's not though. It goes through a router which has a firewall, which is the exact feature you're presumably wanting from a NAT but without any of the annoying downsides.

What fearmongering? There were a bunch of articles about how we were going to run out of IPv4 addresses, and we have now essentially run out of IPv4 addresses. There's a reason everyone is being a dynamic IP address and hosting servers is hard these days.
