|Egress spoofing summary|
|Largest spoofable neighbor prefix||none|
- Your host is behind a Network Address Translation (NAT) router or firewall which rewrites the source addresses of the test traffic. To test your provider's network further, you must remove the NAT/firewall/router and connect directly.
IPv4 AS Route:
This test run probed the following paths in order to infer your ability to send different spoofed source packets. Each node in the graph corresponds to an autonomous system, i.e. different Internet service providers. NOTE: This graph does NOT show if an AS blocks spoofed packets, only the path taken by received spoofed packets. The IP Path Details are available for this run.IPv4 Adjacent Netblock Testing:
Your host (212.111.9.x/24) can spoof 0 neighboring addresses

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 Egress Filtering Depth:
The tracefilter test found your host able to spoof routable, non-adjacent source addresses through the first 1 IP hop(s).Summary:
The results from all tests are aggregated to produce a summary "State of IP Spoofing" report.Feedback:
