As of the middle of February 2020, the OpenINTEL measurement has been extended to also cover the entire IPv4 reverse DNS name space. Like our other measurements, this measurement runs once every 24 hours. Using this data we hope to gain new insight into how the address space is managed, and to check, for example, consistency between forward and reverse DNS. This measurement adds an additional 1.1 billion data points per day, a data collection growth of over 45%.
