Provides a field-collection field, to which any number of fields can be attached.

GeoIP Role allows to dynamically grant roles to the current user according to his IP address location.
It depends on the GeoIP API module.

GeoIP Role may be used with any other module like Nodeaccess that controls access based on user roles.
