    I was wondering why it is that not all online security scanners can
    determine my real IP.

    For example, cannot determine my real IP, but does seem to
    know that my ISP uses a proxy server. I was actually looking forward to
    seeing the results from this previously unheard-of site, for me at least,
    but as it ( couldn't determine my real IP, it stopped the

    However, can find my real IP in a matter of seconds. Is it
    just a case of the scripting (if that's the right term) at
    being simply better than that at ? Or is there 'more to
    this than meets the eye' ?

    Thanks for your time, and for any information you might have.

    Thanks for that YK. Right after posting my original message, it did occur
    to me that 's scanner address had 'https://' at the front of
    it. I wasn't sure if this was relevant or not, but now I know it is. :)

    Thanks for the information.

    GRC uses a small application called IPAgent to determine your real,
    public IP address, which PCFlank does not. There are also Java and
    ActiveX controls that can determine your real IP, the one bound to
    your system.

    You are correct that some scanners are detecting that your ISP uses
    transparent proxies. (WHY your ISP is using transparent proxies at all
    has me wondering, though.) At any rate, scanning a proxy is pointless.
    They serve some security purpose although I'm wondering if they're
    pulling a Comcast.

    Have you tried
