+> ## Note
+> `.listen` binds to the local host, `localhost`, interface by default (`127.0.0.1` or `::1`, depending on the operating system configuration). If you are running Fastify in a container (Docker, [GCP](https://cloud.google.com/), etc.), you may need to bind to `0.0.0.0`. Be careful when deciding to listen on all interfaces; it comes with inherent [security risks](https://web.archive.org/web/20170711105010/https://snyk.io/blog/mongodb-hack-and-secure-defaults/).
