This page allows AS operators to register their contact details with the Spoofer project. If the project receives a test that we believe needs your attention (because there is evidence in the test that the AS has not deployed Source Address Validation) then our system will automatically notify you with information about the test. This system does allow access to unanonymized IP addresses, subject to manual vetting. The first step is to confirm an email address. After we have confirmed your email address, you will be able to enter the ASNs you are interested in.
