Test run at: 2015-12-15 09:54:43 GMT
Client operating system: OSX
Client IP (v4):
Client AS (v4): 23889 (MAURITIUS-TELECOM-AS-AP)
IPv4 Probes: 93

Egress spoofing summary
Address type IPv4
Private blocked
Routable blocked
Largest spoofable neighbor prefix none

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.

IPv4 Adjacent Netblock Testing:

Your host ( can spoof 0 neighboring addresses

Spoofed IPPrefix
ASN of
Spoofed IP

Meaning of status in Received column:

sendtoThe spoofer was unable to send spoofed headers due to an operating system restriction.

IPv4 Egress Filtering Depth:

The tracefilter test found your host unable to spoof routable, non-adjacent source addresses through even the first IP hop.
The results from all tests are aggregated to produce a summary "State of IP Spoofing" report.
We welcome questions and feedback to the Spoofer Information Mailing List and invite users to join the Spoofer Users Mailing List for discussion and announcements.
