This appears to have started recently - if you go to a user’s profile > admin - their last IP address is shown as prefixed with ::ffff: (and so when you do an ip lookup it does not work).

Awesome - fixed! (I needed to change my server from IPv6 discovery to Static configuration and add the range manually.) Thanks for your help :heart:

Could this be related: [rockerBOO] Express.js req.ip is returning ::ffff:127.0.0.1 node.js, express asked by rockerBOO on 11:14AM - 02 Apr 15 UTC I did add a record to allow IPv6 recently, so could that be it? Do you have IPv6 enabled here?

[image] AstonJ: Do you have IPv6 enabled here? This (meta) is running on AWS as a dogfooding experiment, so it is possible it is not, because as I understand it AWS doesn’t use ipv6 at all.. but we’d need to ask @mpalmer

Meta is now fully IPv6 compatible.

Nice! Were you getting the ::ffff: problem too?

Sorry only just coming back to this. Yes I use HAProxy on the front :slight_smile: Do I need to do anything special on the Discourse side to enable IPV6? On the HAProxy side I believe I have changed everything I need to, specifically: bind *:80 to bind :::80 v4v6 and bind *:443 ssl crt /etc/haproxy/certs/ to bind :::443 v4v6 ssl crt /etc/haproxy/certs/ On http://ready.chair6.net everything passes except for: IPv6 Connectivity - FAIL - Could not connect (to site) on port 443 over IPv6. Any idea what I might be missing?

Try instead using two lines as follows: bind *:80 bind :::80 bind *:443 ssl crt /etc/haproxy/certs/ bind :::443 ssl crt /etc/haproxy/certs/

Hi Michael, updated to: #bind *:80 #bind :::80 v4v6 #bind *:443 ssl crt /etc/haproxy/certs/ #bind :::443 v4v6 ssl crt /etc/haproxy/certs/ bind *:80 bind :::80 bind *:443 ssl crt /etc/haproxy/certs/ bind :::443 ssl crt /etc/haproxy/certs/ But I’m still getting the same thing. Here’s the full report in case it helps.

fe80::6e62:6dff:fe46:abf9 is a link-local address, only intended to be used by a machine on the same broadcast domain as the server. Nothing else on the Internet will ever be able to connect to it. Does the server have a “real” IPv6 address (such as something starting with a 2)?

It looks just fine for me:

I bet a beer you use a reverse proxy and not vanilla Discourse with only the internal nginx
