Outbound spoofing summary (from the client to our server) Source address type IPv4 IPv6 Private - RFC1918 or ULA blocked received Routable ✔ blocked received Largest spoofable neighbor prefix length none /16
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.
