Observed behaviour
In a network environment where both IPv4 and IPv6 are enabled, if a user accesses a self-hosted instance via IPv6, the reported IP address in the background is the private IPv4 gateway of Docker, rather than the actual user's IPv6 address. Users do not encounter this issue when using IPv4.
Reproduction steps
- Configure self-hosting using Docker
- Users access the Web using IPv6
- The administrator panel shows that the user's IP is the private IPv4 gateway of Docker, rather than the user's actual IPv6 address.
