Summary

### Summary `0.0.0.0` was used instead of NXDOMAIN for block responses. On Linux, which is the target platform for netfoil, the `0.0.0.0` is sent to localhost rather than just dropped. ### Impact Unintended traffic could be sent to localhost. Impact depends on running services and firewall rules.
