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
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.
