| 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. |
IPv4 Adjacent Netblock Testing:
Your host (181.215.9.x/24) can spoof 16777215 neighboring addresses (within your /8 prefix)

Meaning of status in Received column:
| no | Packets spoofed from adjacent netblock were not received, probably due to blocking |
| yes | Packets spoofed from adjacent netblock were received |
| yes | Packets spoofed from adjacent netblock were received (but that netblock is within the source AS) |
IPv4 Outbound Filtering Depth:
The tracefilter test found your host
able to spoof routable, non-adjacent source addresses through the
first 10 IP hop(s).
Summary:
The results from all tests are aggregated to produce a summary
"State of IP Spoofing" report.
