Outbound spoofing summary (from the client to our server)
Source address type IPv4

Spoof status key
receivedSpoofed packet was received.Pattern of tests from this IP block indicates a switch from allowing spoofing to blocking it.
rewrittenSpoofed packet was received, but the source address was changed en route.
blockedSpoofed packet was not received, but unspoofed packet was.
unknownNeither spoofed nor unspoofed packet was received.
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. 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.

Meaning of status in Received column:

noPackets spoofed from adjacent netblock were not received, probably due to blocking

IPv4 Outbound Filtering Depth:

The tracefilter test found your host able to spoof routable, non-adjacent source addresses through the first 18 IP hop(s).
Summary:
The results from all tests are aggregated to produce a summary "State of IP Spoofing" report.
