==================
When activating a survey, I don't understand the difference between the Save IP address option, and the Anonymize IP address option.

If Save IP address is activated, the IP address is stored, and if Anonymize IP address is activated, the IP address is not recorded. It seems to me that this refers to the same option but in reverse formulation. Is it the case or is there a subtlety I missed ?

Thanks in advance.

Best,
Jessica Bourgin

Well,
there are four cases to investigate
1. IP = yes, anonymize IP = no
2. IP = yes, anonymize IP = yes
3. IP = no, anonymize IP = no
4. IP = no, anonymize IP = yes
Did you try to see the differences?

In case of 3. and 4. it is obvious that NO IP address is stored
1. Full IP address ist stored
 
2. The last group of the address is changed to "0"

When activating a survey, I don't understand the difference between the Save IP address option, and the Anonymize IP address option.
 

If you "anonymize" an IP in LimeSurvey, only parts of the IP address will be saved.

This should anonymize an IP address to a /24 subnet (IPv4) or a /64 subnet (IPv6)
For instance, the IPv4 address 192.168.178.123 is anonymized to 192.168.178.0.
The IPv6 address 2a03:2880:2110:df07:face:b00c:0:1 is anonymized to 2a03:2880:2110:0:0:0:0:0 (changing the last 5 blocks to 0)

Thanks a lot for your answers!

I must confess that for this one I did not try, since the description for the two options in the tooltips was very similar and I did not find the information in the documentation, I assumed I would get the same result.

Thanks for the explanation!

Best,
Jessica

I think this is another case for having just one setting with 3 options:
1. IP address saved
2. Shortened IP address saved
3. No IP address saved

These settings that influence one another and in some cases don't even make sense (cases 3 and 4 from Joffm - this should be one setting, because if you do not save the IP address there is no difference between those two).

I answer at the LimeSurvey forum in my spare time, I'm not a LimeSurvey GmbH employee.
