We have a Discourse installation, carried forward for several years but currently on the latest version (2.4.0beta2) using the latest Docker image, on a public IP address, no proxy or other things in front, LetsEncrypt certs. Sometimes user registration IP and last IP works perfectly, sometimes it …

[image] calmh: Does Discourse not understand IPv6? Discourse definitely does, but you’d need to configure your server and whatever else is in front of it so that IPv6 is functional, etc.

IPv6 is very functional, and using the recommended Docker images setup with the web + data templates. There is nothing else in front. What is there we should tweak? Mind you, out container yml has been around for a few years, although it includes the latest templates and the images themselves are r…

Looks like other people running the default docker setup have the same issue. [image] Remote users IPV6 address shows as localhost support When a user is signed into the forum under an IPV6 address their IP shows up as 127.0.0.1 in the administrator panel. …

Hard to say. I just audited the last ~8 new users who signed up at talk.commonmark.org which is a very default standard install and they all had valid IPv4 addresses for Last IP and Registration IP (sometimes the two differed, as well). I know if user accounts come in through SSO or other unusual a…

Were any of those addresses IPv6?

Nope, none of them were, but I don’t know if this colocation host even does IPv6.

Then I’m sure it won’t exhibit the problem of showing localhost instead of IPv6 addresses for users who come in over IPv6. Doesn’t mean the problem doesn’t exist.

Problem doesn’t exist on Discourse official hosting, at least, and that’s IPv6 capable. Nor do I see problems on a vanilla install at a random colocation host. Not sure what else to tell you, other than you didn’t answer my rather important question [image] codinghorror: I know if user accounts…

Ah, yes, those are regular signups, no SSO or associated accounts. [00] I don’t doubt that it works in your hosting, but you don’t use the “standard” Docker setup that most users do, I think? I mean, I’m sure it’s possible for it to work given a proxy setting the right headers etc, the question i…

I’m pretty sure that you need to add a bit to your app.yml that tells nginx to recognize your ipv6 address and pass through the client address. I haven’t figured out how to do that yet myself, though. The topics about running a reverse proxy have ipv6 examples, which provide hints. This is on my li…
