NeuVector scanner plugin enforces usage of IP address when connecting to a controller. Although, hostname can technically be used, the implementation gives a feeling that it was not an intention.

Enforcing an IP address (or pure hostname) eliminates the possibility to use API exposed under a subpath. Consider the case when controller exposes API as: https://neuvector.company-internal.com/api/

It appears that using URL as controller address may resolve this and other similar needs.
