    Unique Submissions: if the user dynamic IP addresses, does this mean that numerorus submissions can be made from one machine (computer)?

    Asked by ThomasMcCann on January 15, 2011 at 08:03 PM

    When you use the term IP, is it a static/dynamic/both address and if it includes dynamic addresses, does this mean that numerorus submissions can be made from one machine (computer)?.  Also if you are allocated dynamic IPs by your host, could a  submission be rejected from a client because the IP had already been used by a completely different client  on a completely different machine who had previously been allocated the IP address?.  I would like each client to be able to make one submission or make it as hard as possible to make multiple submissions.

    Yes, that's true. If the user has dynamic IP address, they will be able to re-submit again when their IP address changes. If you think that's a common problem, you should then use the cookie check instead of strict check.

    How do you use the cookie check (is this loose check?)?.  How does it work?

    It sets a cookie and when the user comes back from the same browser checks if the cookie exists. Yes, that's loose check.
