What networks does Honeygain work on, and what does the ‘Unusable network’ error mean?

Honeygain supports all IP types, except for data center (DCH) and reserved (RSV). If you try to connect using a DCH or RSV IP address, you will see the ‘Unusable network’ error, and the application will be stopped until you connect to an appropriate network.
