> I don't think this is inherently a problem. [...] My router for example has a similar UI to forwarding a port with IPv4 and opening the port for IPv6. Glad to hear that you don't have a problem with your router, but how does that relate to GPs problems with theirs?

It isn't. But It's also not an answer to GP. The solution for them is "get a better router" because the problem is not the IPv6 protocol. Opening a port is not harder than creating a NAT forwarding and if your hardware can't do it then it's bad.

Exactly, and “there are a lot of bad v6 implementation CPEs out there” is an important data point worth acknowledging.

Everything that's needed besides letting computers talk to each other, that is. With ipv4 you have a two tier internet. Computers talk to servers, servers talk to servers, computers can't talk to computers so every video call must be routed through a server.

I hear this as a cited as a benefit of IPv6 a lot. Honest question: Isn't this at least a privacy issue, at most a security issue? SLAAC seems like what we already have with extra, breakable steps, which doesn't effectively address the privacy issue anyway.

Everything useful is a security issue. Security is a trade-off, not a positive stat you maximize. Every security tightening removes some utility from a system; the hope is that this disproportionally disrupts the "bad actors" over "good ones".

(All of that hinges on the key question that people seldom ask: what is being protected, and from who. The "two-tier" Internet is, in a way, pointing out a case where regular users are seen as threat actors.)

For client server web browsing what's the downside of CGNAT? I'd understand if we were talking about self hosting a service from home but for typical consumer usage?

1. Peer-to-peer networking won't usually work correctly. And quite a bit of software uses P2P networking these days---BitTorrent, Zoom/Teams (via WebRTC), Tailscale, PlayStation/Xbox multiplayer, etc. Most of these services have automatic fallbacks when P2P networking doesn't work, but these fallbacks are usually slower and less reliable. 2. Most websites assume that 1 IPv4 address==1 household, so you'll often run i…

1) my stateful firewall is going to break most of that anyway

2) if cg nat is as popular as people claim then they won’t be doing that as it’s not an edge case

Where's the privacy issue? That the server can figure out that two computers in the same house are different since your laptop and phone no longer share the same ipv4 address but instead have two ipv6 address? Your phone and laptop can just have multiple ipv6 addresses and rotate through them regularly... as apple does by default https://support.apple.com/en-ca/guide/security/seccb625dcd9/... Security? NAT is not a f…

They used to recommend using the MAC address. This was ok 30 years ago when a computer sat in an office on a desk but it makes it very easy to fingerprint a moving computer as it moves across different networks.

Using a random address (Privacy Extensions) solves this problem though, but do we expect everyone to know what that is and check it's enabled? Mine wasn't enabled by default (on Linux) and I only noticed when a bittorrent site warned me.

> a better web experience than IPv4 That's already the case. IPv6 is often faster because most ISPs these days use cgnat for IPv4.

In my experience not true in practice cause I have experienced way more issues with the IPv6 endpoints of sites than their IPv4 counterparts. This becomes noticeable when pipelines on IPv6 connected servers suddenly have random request/post failures to public services. Then either the whole service is temporarily having issues or there are a few bad IPv6 endpoints while all the IPv4 endpoints are fine. Seemingly this…

I have been on a dual stack IPv4 and IPv6 connection for a while now. IPv6 is the preferred protocol. I think I'd have noticed if there were widespread IPv6 issues. It used to be worse, but that was years ago.

Interesting to see the per-country rates[1]. France is up to 85%, apparently! [1] https://www.google.com/intl/en/ipv6/statistics.html#tab=per-...

The more mobile traffic, the more IPv6. Have a look at India, it is not as if everyone has a fibre connection running IPv6.

Here in Belgium it's the other way around. we've had IPv6 for over 10 years for basically all home internet, but mobile is still ipv4 only. Not sure why since it's all the same companies.

Specifically on weekends, which seems to indicate that it's the corporate/business network side of things that is not bothering with implementing it.

You frame "not bothering" as if its a checkbox with "enable IPv6" to check and all done...

Put all work into reorg, for what? Some numbers to change? Why when IPv4 works?

Anyone know why there is a high frequency signal on top of the long term trend in that graph? https://www.google.com/intl/en/ipv6/statistics.html#tab=per-...

People connect through cellphones more on weekends, and cellular has higher IPv6 usage.

Just to add to the 'but the ISPs do not' anecdotes, it has been six months since someone last commented so it is probably time to mention this again on Hacker News:

* https://havevirginmediaenabledipv6yet.co.uk/

A major ISP in the U.K., that said in a public statement on World IPv6 Day in 2011 that

> As well as our core and access networks being capable of supporting IPv6, we're rigorously testing our entire network to ensure that all customers have a smooth and simple transition when the time comes to flick the switch and turn IPv6 on. We're really pleased with how our tests are advancing and are happy to say that by the end of 2012, we'll be able to fully support customers looking to switch to IPv6.

has not managed to actually flick that switch in 15 years.
