Comment 2 for bug 1550644

Blake, I like that idea; furthermore, I think we should store the origin of the address, that way in the future if we support other mechanisms of network configuration (networkd, networkmanager, a routing protocol daemon etc) we can figure out which subsystem "owns" the address.

For example, today we would maybe have an "eni" and an "iplink" type; in the future we could have "networkmanager", "networkd", etc.
