Outbound spoofing summary (from the client to our server)
Source address type	IPv4		IPv6
Private - RFC1918 or ULA	blocked		blocked
Routable	blocked		blocked
Largest spoofable neighbor prefix length	none		none

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.

Meaning of status in Received column:

no	Packets 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 1 IP hop(s).
