Use IP-Range as Object Precondition

If you need any help in filling out this wiki page, please visit our ILIAS Community FAQ. And please complete the metadata information in the right column after having created the page.

1 Initial Problem

Starting from ILIAS 10, Tests can be restricted by IP address ranges (instead of the previous binding to a single IPv4 address). While this is particularly useful for tests being held in e.g. computing pools of schools and universities, we feel that this is could be extended to e.g. entire courses that shall only be completed on computers whose network address is in a particular range (and, by extension, computing pools). Leveraging course preconditions for this even allows to make different objects accessible to learners in different rooms by putting them in separate courses (and configuring the courses to be hidden if their preconditions are not met).

2 Conceptual Summary

We feel that this could be implemented by extending the functionality of Test: Add IP Ranges as Access Constraint to Test Settings in order to make it a supported Precondition.

4.3 Privacy

ILIAS checks the IP of a user, if the IP is inside or outside the defined range. But this is not a new date.

4.4 Security

This feature does not have negative security implications. Some could think this makes the access to a specific test, where the setting is activated, safer.
