   * This confirms the returned connection is healthy before returning it. If this encounters any
   * unhealthy connections in its search, this will clean them up.
   *
   * If [routes] is non-null these are the resolved routes (ie. IP addresses) for the connection.
   * This is used to coalesce related domains to the same HTTP/2 connection, such as `square.com`

Aquí la variable `app` será un instance de la clase `FastAPI`.

Este será el punto de interacción principal para crear todo tu API.

Esta `app` es la misma a la que nos referimos cuando usamos el comando de `uvicorn`:

<div class="termy">

```console
$ uvicorn main:app --reload

Puedes crear aplicaciones listas para producción con **FastAPI** ahora mismo (y probablemente lo has estado haciendo por algún tiempo), solo tienes que asegurarte de usar la versión que funciona correctamente con el resto de tu código.

	// - the CmdAdd comes back thru here with a new IP
	// - we will never clean up that old IP that we "lost"
