So the code has:
    fans, err := cfg.FanConfig()
    if err != nil {
        return errors.Trace(err)
    }
    if len(fans) == 0 {
        return nil
    }

So it should only be trying to CalculateOverlaySegment if FanConfig is not
empty.

I know we do some amount of autodetection of whether we *could* run the
fan. Can you make sure that fan-config is set to "" ?

What I also don't understand is that the CalculateOverlaySegment is also
doing:

if underlaySize <= subnetSize && fan.Underlay.Contains(underlayNet.IP) {
...
  newFanIP := underlayNet.IP.To4()

I don't quite see how fan.Underlay would end up saying that its CIDR
"Contains" an IPv6 address.

I know we do some amount of "autodetect what a possible fan config could
be", but I haven't found that code yet. It's possible we implemented
something on Openstack that somehow automatically generates fan config that
includes IPv6 addresses, when we know that it never should.
