Can i somehow limit one survey filled out per ip address on an open / public survey?


I want to have an open survey, but prevent multiple responses from one ipAddress

Not possible in LimeSurvey (at least not in the vanilla version). Someone asked some time ago the same thing here: forums.limesurvey.org/forum/can-i-do-thi...nly-be-accessed-once

Keep in mind that IP addresses are not always unique per respondent. E.g. in a company, school, university a lot of people are behind the same IP Address.

Also, if a respondent wants to respond various times the IP limit is not necessarily preventing this:
E.g. I can answer from my home network and from my work network and also from my mobile phone. At work I even have two different IPs. Then I could switch off my modem at home and the provider will assign a new IP address and I could go again. Or I can use a VPN to answer, go to a public hotspot, etc.

In my opinion: Not even worth the effort. Usually people do not want to answer twice anyway and should they really want to, they most probably will find a way around your IP limitation. In my opinion it create more problems than it solves.

ya, i actually did see that thanks... just had a need for it (all home ip's and one per).

if not, i'll do the cookie method.

You would have to create your own application that checks the IP against IPs previously used. This might prevent a few people from taking part twice, but only the ones with very little motivation and very little knowledge in IT.

Maybe it could be also solved with a custom plugin. But to be honest, the effort and cost involved would probably not worth it, for the above mentioned reasons.

It would be like adding a better lock to your gate, but leave the wholes in the fence.
