Hello,
I'm trying to see if Qualtrics has the ability to prevent multiple submissions/responses based on the participant's IP Address. My organization is looking for specifically this, not using a browser cookie as this can be bypassed using an incognito window.
Right now, we have to go manually discard flagged responses. Instead, we would like participants to see a message that says something similar to, "You have already completed this survey."
Any help is greatly appreciated, thank you!
How to Prevent Multiple Submissions based on IP Address?

The out-of-the box options I'm familiar with (Ballot Box Stuffing prevention) work off of cookies. You can easily circumvent this with an incognito window, but I also think it's worth noting IP address can be circumvented with a VPN if you're concerned about workarounds...
Explore the Relevant ID function: https://www.qualtrics.com/support/survey-platform/survey-module/survey-checker/fraud-detection/#RelevantID This may give you a bit more to go off of!
