# Measurement Information and Usage Notice

This website is operated and maintained by researchers of the [Software
Security Group](https://informatik.rub.de/softsec/) in the [Faculty of
Computer Science](https://informatik.rub.de) at [Ruhr University
Bochum](https://princeton.edu).

Most likely, you are visiting this website because you have received requests
from our network range that you might consider an attack or scan. Please note
that the requests we are conducting from these IP addresses are benign and we
are not attacking you or anyone else.

At almost all times, we are running a variety of different experiments and
scans from our network to evaluate and assess the global characteristics of
the Internet and its security and privacy posture. Our current experiments are
detailed below.

We hope that the information below answers your immediate questions and ease
your concerns. However, we understand that they might not answer all your
questions. Therefore, if you wish to receive additional information about our
research projects impacting you or if you wish to be excluded from our
measurements, please reach out directly to us by email to
[[email protected]](mailto:[email protected]) with the
relevant information (source/destination IP address, address range, what has
impacted you, etc.). We will be more than happy to provide more information
about our research project and/or exclude you from our experiments through our
blocklist. Finally, please note that we store collected data for research
purposes only and that we only store aggregated and anonymous statistics
whenever possible.

# Current Measurements

  * Liveness checks for selected IPv4 and IPv6 address ranges and ports.
  * TLS handshakes for selected IPv4 and IPv6 address ranges and ports.

# Measurement Hosts

We currently perform measurements from the following hosts:

  * ports.measurements.softsec.rub.de (IPv4: 185.73.23.133)
