Warnings:

⚠️ Your host is behind a Network Address Translation (NAT) router or firewall but spoofed packets are still being received without modification. See here for more information.

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.

IPv4 Adjacent Netblock Testing:

Your host (185.66.194.x/24) can spoof 4194303 neighboring addresses (within your /10 prefix)

Meaning of status in Received column:

yes Packets spoofed from adjacent netblock were received
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.

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).

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.

yes	Packets spoofed from adjacent netblock were received
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.
