Sean R. Owen commented on SPARK-43366:
--------------------------------------

Ack yeah, nevermind. Reading too fast without coffee. That I don't know, except 
to say that's not going to be controlled by the _driver_ IP. Block manager 
would be tied to _executors_. Is that IP an executor?

> Spark Driver Bind Address is off-by-one
