Outbound spoofing summary (from the client to our server) Source address type IPv4 Private - RFC1918 ✔ rewritten Routable ✔ received Largest spoofable neighbor prefix length none
Spoof status key 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:
rewritten The source address of the probe packets we received differs from the spoofed address. It appears that an intermediate device is rewriting your packet headers.
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.Feedback:
We welcome questions and feedback to the Spoofer Information Mailing List and invite users to join the Spoofer Users Mailing List for discussion and announcements.
