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.

IPv6 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. If non-spoofed packets weren't received at a destination, the traceroute to that destination is not included in this graph and may even cause a totally empty graph.

IPv6 probes:

Spoofed source address	Destination	Received

Meaning of status in Received column:

yes	Packets spoofed from adjacent netblock were received (but that netblock is within the source AS)
natblock	Spoofed probe packets appear to be blocked by your local NAT or firewall rather than being rewritten with a public source address.

Summary:

The results from all tests are aggregated to produce a summary "State of IP Spoofing" report.
