tracksessionip
From MoodleDocs
Martin Langhoff
- "It restricts a single session from changing IP, and this is mostly a debugging tool for a strange problem that we think is a PHP bug. It does not stop a single user from having more than one session."

Config.php
- to turn it on, go to config.php and uncomment:
- $CFG->tracksessionip= True;
// If this setting is set to true, then Moodle will track the IP of the // current user to make sure it hasn't changed during a session. This // will prevent the possibility of sessions being hijacked via XSS, but it // may break things for users coming using proxies that change all the time, // like AOL.
