Review Comment:
   I don't think `allowed_netloc` should be initialized here. The variable 
itself makes sense, but it should be computed inside the `async run()` method 
where it's actually used. Initializing it here unnecessarily couples this code 
to the connection lookup and may perform work earlier than needed.
