Internet Wide Scanners Wanted

In our data, we often find researchers performing internet wide scans. To better identify these scans, we would like to add a label to these IPs identifying them as part of a research project. If you are part of such a project, or if you know of a project, please let me know. You can submit any information as a comment or via our contact form. If the IP addresses change often, then a URLs with a parseable list would be appreciated to facilitate automatic updates.
