Outbound spoofing summary (from the client to our server)
Source address type	IPv4
Private - RFC1918	blocked
Routable	received
Largest spoofable neighbor prefix length	/8

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 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 Adjacent Netblock Testing:

Your host (50.2.184.x/24) can spoof 16777215 neighboring addresses (within your /8 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).

Summary:

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