Server Version#: 1.25.1.5286 Player Version#: 4.70.0 (app.plex.tv) How to reproduce: full dual stack WAN with public IPv4 address (say, 11.22.33.44) dual stack LAN, Plex server also dual stack (192.168.x.x & IPv6 GUA) either UPnP-IGD active, or a manual port forward set on the gateway towards th…

Question: Is the host also dual stack and which IP address is used for the primary adapter ; IPv4 or IPv6 ? I have dual stack host, LAN, Modem/Router (DNS resolver), and WAN. I have the host adapter configured with IPv4. ISP favors IPv6 as primary, IPv4 secondary. PMS correctly shows IPv…

[image] certuna: set the server’s DNS resolver How was this set? Plex is using musl libc, and expects to find a valid configuration in /etc/resolv.conf.

@Volts Manually, this server address is indeed stored in /etc/resolv.conf

@ChuckPa Yes, the host (PMS server) is dual stack, with both IPv6 and IPv4 on the (only) interface. DNS server set manually on the Plex server, I’ve also tried it with setting the same DNS64 server as the upstream resolver on the router, same behaviour. PMS on Windows, Linux and macOS. I’ve reboote…

[image] certuna: Update 1 :+1: That’s how the address detection works. Plex uses DNS to look up the service, and makes a connection to it. The plex.tv service reports the address that connected to it. It’s common (and typically recommended) to prioritize AAAA when both AAAA and A exist. But…

[image] Volts: plex.tv has no AAAA record; MyPlex doesn’t support AAAA/IPv6. Is this maybe something plex.tv can reconsider? Over 25% of the world is dualstack now, significantly more in some economies. India is 75%, the US is 47%. For most of these users the v4 is behind a carrier grade nat …

I think I’m confused about your setup and goals. If you have dual-stack LAN and WAN, why are you using a DNS64 service? The goal is to move as much traffic on the local network to IPv6 so IPv4 can be disabled on most devices - it’s a lot easier to manage that way. At this point Plex clearly stil…

I’m with you in theory. In practice that sounds like a mess. :slight_smile: Except DNS64 isn’t intended for dual-stack hosts. RFC6147 calls this out in Section 6.3.2 . And there have been other discussions about how to best manage mixed IPv6-only / dual-stack environments: https://tools.ietf.or…
