Allowed Networks and IPv6 CIDR Notation

Server Version#: 1.15.1.707-d893009fb
Player Version#: WebClient Version 3.83.1

IPv6 CIDR notation is not supported in the allowed Networks field
Error parsing allowedNetworks ‘####:###:#X##:##X::64’: Invalid argument

Where the actual value is ‘####:###:#X##:##X::0/64’

Was it working before you upgraded? According to this it is broken:

I cannot say for sure. The interface was quite unstable so I started going to the logs to determine why and alas they have been rotated too swiftly for me to tell

IPv6 isn’t fully implemented / supported in PMS yet.

It’s being worked on now.

If the ISP provides IPv6 only, your best bet is to run an IPv4 LAN, with IPv6 disabled in Settings - Server - Network because none of Plex’s servers use IPv6. IPv6 buys nothing at this point except difficulties.

We don’t all live in the 1970s. IPv6 works fine with PMS, about 50% of my streams are over v6. The Plex authentication servers not supporting v6 is mostly unrelated because when configured correctly at DNS and with a “custom server access url”, Plex clients can prefer v6 and connect directly to the server through that.

No, we don’t live in the 70’s. They were a good times. I remember them well.

I stated the current state of Plex’s implementation, for better or worse.
