@Marvin is it possible to bind prefect to the :: ipv6 address?

Currently, Prefect does not explicitly support binding to an IPv6 address due to the default behavior of binding to

0.0.0.0

, which is IPv4-specific. This limitation is highlighted in a GitHub issue where users deploying on IPv6-only environments face challenges. The issue suggests introducing an environment variable to customize the bind address, but as of now, this feature has not been implemented. For more technical details, you can follow related discussions and updates on the Prefect GitHub repository: - Allow customization of worker bind server addr - Cannot start Orion `FastAPI` app: `Cannot assign requested address` If you're planning to deploy Prefect in an IPv6-only environment, you might need to consider workarounds, such as using a proxy or a dual-stack network configuration, until explicit support is added.
