The IPRangeSurvey-Plugin grants access to a survey only for people within a certain range of network addresses. This can be useful if people should only be allowed to execute a survey e.g. within the company’s network.
A similar plugin to restrict access to the admin interface is available for download as well: https://survey-consulting.com/product/limesurvey-plugin-ip-range-login
