About Us

We are a dedicated team of computer science researchers and students who are focused on studying Internet filtering and its implications. Our research gathers data that is publicly accessible on the Internet to anyone. The purpose is to analyze the security and availability of deployed Internet systems. This data helps identify widespread vulnerabilities and can assist system administrators in adopting best practices or addressing potentially harmful configurations.

Our Server

Our servers perform Internet measurement scans using powerful network scanners like ZMap. It's important to note that the packets sent from us are harmless probes designed solely for academic research purposes. We have no intention of exploiting or attempting to log in to any services.

Opting Out

If you are observing network packets that meet the following criteria and you wish to opt out:

  1. Packets sent from our servers (a) that direct you to this page upon visiting their IP(s) and/or (b) whose DNS PTR records point to this page.
  2. Packets containing domains like research-optout.np-tokumei.net.

Please get in touch with us by sending your network logs to [email protected]. Your cooperation is greatly appreciated!
