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.

Warnings:

⚠️ Your host was unable to source even non-spoofed IPv6 UDP traffic to our servers. A firewall, router or other middlebox is preventing our testing. To test your provider's network further, you must remove the firewall or router and connect directly.

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.

Meaning of status in Received column:

sendto The spoofer client was unable to send spoofed headers due to an operating system restriction.
