Note that security tests depend on determining your computer's IP address. If your IP address is incorrectly determined, the wrong machine will be mistakenly tested.  This may be your ISP's proxy.  Computers with multiple network connections can have more than one IP address. And machines with only one IP address can have it effectively "hidden" or "masqueraded" if the connection passes through any sort of firewall, proxy server, or other buffering agent. A Free IP Agent at http://grc.com/ describes this issue.  Note that this IP Agent applies only to tests at that site.

The SANS (System Administration, Networking, and Security) Institute is a cooperative research and education organization through which more than 62,000 system administrators, security professionals, and network administrators share the lessons they are learning and find solutions for challenges they face. As a part of this effort, SANS offers a series of exceptional educational conferences featuring up to eight days of in-depth courses and multi-track technical conferences focusing on user experiences and problem solving. SANS also produces a series of cooperative research reports, electronic digests, posters of authoritative answers to current questions, and cooperatively-created software.
