Anyone outside the network subtree accessing anything except the api module is
in risk, as internals may be changed or removed. It is equivalent to accessing
a private attribute in python.
In general I am not in favor of contacting the network package for things that
are not really its main business logic. Asking it if an IP is under one of the
networks it manages seems fine, but asking this in general for the host is
something else.
This could fit a helper in common.network, but we'll need execCmd moved to
common first.
Thanks,
Edy.
