Hi,

An option that lets the survey creator choose if to collect full IP or part of it to the survey

www.limesurvey.org/manual/Notifications_...data#Save_IP_address

Else : if need part : not a core task, must be a plugin.

4.2 will have a new feature that will allow you to anonymize the collected IPs (it will be released on the 20th of April)

What is the usercase for saving partial IP addresses in a survey? Any kind of tracking?

It's like eating the cake and keeping it whole.
When wanting to keep the users anonymity but still know where they come from for statistics or see if they made false vote about their place of residence for example...

p.s.
I'm curious how this feature will be, if with flags that will show IP's country or not.

That would be another feature request. Currently you will just seen parts of a IPv4 or IPv6 address replaced with eg. 0.

Adding a country information to the responses would be a complete different feature request.
A IP GEO database would be needed. Bundled or via API.

BTW: If the respondents are known via invitations the obfuscated IP might be enough to identify them.

I don't know what to write in the feature request because I don't know how it looks like.
Do you know how the system will show the IP's?
Is it per answer/poll or admin doesn't see it?

What is the difference between invitation with or without obfuscated IP?
It means that when using invitation + obfuscated IP, the survey cannot be anonymous?

And you cannot rely on it.
You only know where the survey was answered.
What if somebody answers your survey during his holiday in South Africa, but his "place of residence" is Finland?

We will know, when LS 4.2 is released. My educated guess is that you just see the IP in the responses set like today. Only the last parts are obfuscated. Anything beyond that would be not scope of the current feature description.

If you have in your invitation list only one person from a country/company, even the obfuscated IP can allow to match response to that person. It is better that the full IP, but there will be cases where you still can match people.

Right.
It also depends on the question.

Where the problem lies?
I mean, who can match people, the admin, other respondents or hackers?
And if just respondents than, add option to only show IP after "x" votes.
