6 months ago I've no idea why it's happening, it's a very weird scenario for me. Looks like your network Gateway IP is set to fddb:21e4:36d4:1::1/64 instead of fddb:21e4:36d4:1::1, /64 it's supposed to be set at t he Subnet, not at the Gateway IP.
The behavior is related to that snippet of code
Please, check your network configs by running
$ docker inspect networkNameMy example bellow (I wasn´t allowed to create the network with an invalid gateway IP, but don't know, maybe it was possible in past versions of docker).
$ docker network create --subnet="fddb:21e4:36d4:1::/64" --gateway="fddb:21e4:36d4:1::1" --ipv6 trash1
$ docker network inspect trash1

The IPv6 gateway and subnet is automatically assigned by Docker in my case, I've just configured the pools in the Docker config:

If you are still getting the the issue, please change the log level to TRACE, simulate the scenario and attach the logs.
Then execute the command bellow with the network id of the network logged at status=bestNetwork, network=$NETWORK_NAME, ip= right before the exception and attach the result.
$ curl -X GET --unix-socket /var/run/docker.sock 'http://localhost/v1.21/networks/$NETWORK_ID'Hm, I've upgraded to 3.16.3 and set log level to INFO, but it seems that I'm not getting these errors anymore. I also did a bit of rework of the dns proxy setup since I started with it, so that could be related as well.
I'm sorry, I don't have anything else for you. Feel free to close this issue and I'll reopen if it starts again.

4 months ago Hello @mageddo, I'm still seeing this issue. Usually after the container is created, it's not possible to resolve it. Tried with the latest DPS version 3.19.5. When looking at the docker network inspect, there's is this weird address :( "Gateway": "fddb:21e4:36d4:9::1/64". Other networks don't have the /64 in gateway, not sure when it disappears :/

4 months ago It really looks like an unwanted behavior from docker, but I wasn't able to find a issue on docker repo related to it. Can you upgrade your docker version to check if it fixes your issue?
If wouldn't fix that issue, then I can work on a workaround at DPS IP mapping to remove the '/64' at the end.

4 months ago The OS is fully updated Fedora 39, Docker is provided by moby-engine-24.0.5-1.fc39.aarch64 package, which is an upstream for Docker. I use ansible to manage the containers, so there's also the latest community.docker 3.10.4 ansible collection and on the managed host, the python library python3-docker-6.1.3-1.fc39.noarch. I guess the issue can be anywhere here.
The moby-engine on Fedora is supposed to be better integrated with the OS, but they have some issues with upgrading to the newer version, so it's still in the works.
Currently I'm not able to reasonably update anything further. I don't have Fedora 40 yet on the servers, but the moby-engine version is the same.
