Ongoing Projects

• University of Michigan. J. Alex Halderman's team hosts the scans.io repository, develops the ZMap scanner, and regularly publishes new data to correspond with their research.
• The Meta Intelligence Project. A new project that is uploading its datasets to https://scans.io/

Public Datasets

• DNS Census 2013. This project compiled a list of over 750 million host names using a variety of sources.
• Critical.IO. The Critical.IO scanning project ran from May of 2012 to April of 2013. The data is broken up by month and protocol and covers a mix of TCP and UDP services.
• Internet Census 2012. This static dataset was collected illegally through the Carna botnet built for this purpose. An interesting reference point and a great source of statistics all the same.
