Currently the auto_ip logic checks for a public v4 address to determine
if it should make a FIP. However, we have richer logic that provides
interface_ip that takes in to account IPv6 as well as configured choices
as to what the "default" network should be. That is what should really
be cared about - does the server have an ip that would be considered the
thing to connect to it on.
