The module helps to determine geographical address by IP using dadata.ru service. This service provides address information for Russian IPs. It provides accurate results and correct location names in Russian.
Dadata.ru is commercial service and auth token is requried to use it’s API. But 10000 daily requests to it’s API is free and due to local database caching this should be enough for most sites.
The module provides an API for other Drupal modules.
