Methods and apparatus for updating data for printing devices are provided. A device state management system (DSMS) can send probe messages to printing devices. The DSMS can receive responses to the probe messages, where the number of probe messages can exceed the number of responses. After receiving the responses, a number of unconfirmed printing devices can be determined based on data stored in a device database (DDB) associated with the DSMS. The DSMS can determine a system-instability value associated with the number of unconfirmed printing devices. The DSMS can determine whether the system-instability value exceeds a threshold. After determining that the system-instability value exceeds the threshold, the DSMS can: determine address clusters associated with the unconfirmed printing devices; send probe messages to addresses within at least one address cluster; receive responses to the probe messages; and update the DDB using data in the responses.
