Any user, whether logged out or logged in, will have a unique session ID. This ID is passed on every page request.

He therefore would has all the rights in the system that owns the original user. To prevent this abuse, Admidio compares additionally on every page request, the associated IP address to this session. If the IP address changes in between, so Admidio recognizes this as an invalid connection and closes the corresponding session.

This setting is deactivated by default, as it can cause problems for users. For example, some users intentionally use services that regularly change the IP address. It can also happen that some providers deliberately change the IP address after a certain period of time.
