IPv6 and NAT64

[x414e54]

I am having some issues connecting to Steam on IPv6. My home connection uses NAT64 which translates the old fashioned IPv4 addresses to IPv6 and allows me to connect to IPv4. Internally my network is single stack IPv6 so my computer does not have an IPv4 address other than loopback.

Programs such as Chromium and Firefox work correctly on IPv4 and IPv6 sites.

+1 on this.
My entire network is pure-IPv6 (+NAT64 at a gateway/ISP level) and Steam is one of the three appications I've found in months that assume there's native-IPv4 connectivity.

This issue is critical, as it does not allow users to even log into steam, and there's absolutely no workaround.

Steam still doesn't work on NAT64. Most incompatible applications work with a sock proxy which has access to IPv4 internet, but Steam doesn't support it, even as a system-wise setting.

[WhyNotHugo]

Entire months being unable to play any game with absolutely no workaround is an extremely critical issue (and reflects the issues of propietary distribution mechanisms such as Steam). Is there an ETA on this?

Steam does not work over IPv6-in-IPv4 (RFC4213), testing now using HE.NET tunneling (no IPv4 connectivity here), only some parts work - like chat

Really? I've found that authentication does not work on IPv6 (even with NAT64). How did you manage to log in with no IPv4?

I don't know, it just worked! I cannot retest, different router and location

IPV6 issues opened in 2013 - still valid in 2017.. says heaps about how much Valve cares about its clients. Sitting here on IPV6 only network, unable to use any of my purchases because it's steam is clearly connecting based off hardcoded IPV4 addresses rather than using hostnames otherwise DNS64 would have kicked in and I wouldn't be writing this.. 4 years after the first time this issue was opened.

Please put some effort into this. 4 years is enough time to put such a core issue on backburner.

+1 for this. IPv6 should be available for steam in 2017.
Please make this happen.

+1 ... 2019 is approaching!

[treysis]

And still a no-no. At least on Linux. Didn't try Windows.

Classic Volvo.

+1 ... 2020 is approaching!

I'm affected as well by this. As my IPv4 connection (DS-lite) of my cable provider is not 100% stable, I hoped that Steam would just use IPv6, but no, it doesn't work at all. If IPv4 is down, Steam refuses to start.
