| received | Spoofed packet was received. | ✔ | Pattern of tests from this IP block indicates a switch from allowing spoofing to blocking it. |
| rewritten | Spoofed packet was received, but the source address was changed en route. |
| blocked | Spoofed packet was not received, but unspoofed packet was. |
| unknown | Neither spoofed nor unspoofed packet was received. |

Meaning of status in Received column:
| natblock | Spoofed probe packets appear to be blocked by your local NAT or firewall rather than being rewritten with a public source address. |
IPv4 Outbound Filtering Depth:
The tracefilter test found your host
unable to spoof routable, non-adjacent source addresses through
even the first IP hop.
Summary:
The results from all tests are aggregated to produce a summary
"State of IP Spoofing" report.
