@matushorvath as ChuckPA said previously and just reiterated, IPv6 support is “on the list”. I’m just as frustrated with the state of progress regarding IPv6 on Plex as anyone. I’m also frustrated that my ISP wants to charge me for an IPv4 address after I had one originally and they took it away to put all customers behind CGNAT.
I’m sure you can understand Plex devs not giving an ETA as you are a software dev yourself. The best I can do is encourage you to vote for the feature here: Ipv6 support for myplex - #212 by RedWolf. That will help the devs prioritize their efforts and show our need for IPv6 support.
Maybe @ChuckPa can put us on a special list for beta testing IPv6 support when it is ready!?
