Sounds like you want to be using Views, with a `view:` block which has
`view-first: yes` set, local-data: in the view providing the IP address
of the server, and a set of `access-control-view:` directives putting
individual IPs into that view.

I'm not seeing anything under
http://unbound.net/documentation/pythonmod/index.html which shows the
access-control or view directives being exposed to Python.

Assuming that the list of IPs is fairly dynamic, have you considered
using an include directive such as:

  include: "/etc/unbound/python-managed.d/*.conf"

and then having your Python be a standalone service to
modify/create/delete one or more files in that directory based upon your
site integrations, and use unbound-control to
dump_cache/reload/load_cache ?

I don't see unbound-control options to directly change
access-control-view: options without doing a full reload.  :\
