IP assignment and DNS issues typically correlate, at least in our internal infrastructure: If foo.example.com resolves to 1.1.1.1, but 1.1.1.1 resolves to bar.example.com, there's likely an IP conflict where two distinct hosts have been assigned the same IP. Vespa itself also has strict hostname validation on startup, where hostname and IP are resolved and compared. That's another reason we do this check during allocation as the node would refuse to start in case of misconfiguration anyway. | public NodeCandidate withNode() {
