GINO

Global INternet Observatory

Motivation

Internet measurements have long been a research priority at our chair. These measurements help us better understand the Internet and its security.

GINO is a research group for exchanging ongoing research, concepts, and ideas in the Internet measurement domain. Researchers and students meet once every month to discuss current topics, advancements, tools, and best practices in measurements.

Internet-wide scans

We conduct various regular and ad-hoc Internet-wide scans for protocols such as HTTPS, DNS, and BACnet. These are purely scientific and we never attempt to intrude into any system. We follow best practices laid out by the scientific community such as by Dittrich et al. 1, and Partridge and Allman 2.
If you are affected by these, e.g., because of IDS alerts, please contact us and we will be happy to blacklist you immediately. The involved machines are:

Host IPv6 address IPv4 address
planetlabX.net.in.tum.de 2001:4ca0:108:42::X 138.246.253.X
dallas 2600:3c00::f03c:91ff:fe3b:d2d 45.33.5.55
singapore 2400:8901::f03c:91ff:fe3b:d08 139.162.29.117

For a brief time in February 2018, the rDNS pointer for planetlab19.net.in.tum.de. points to researchscan19.netintum.umbrellastudy.com.

IPv6 Hitlist

We provide a daily updated IPv6 hitlist which can be downloaded by interested researchers. Find more information on our dedicated IPv6 hitlist page.

Monthly GINO meeting

We meet every month for about one hour. The audience of the monthly meetings are:

  • Interested researchers from the chair
  • Interested researchers from other chairs
  • Students currently doing a thesis or project in the area of Internet-wide measurements
  • Students who are interested in doing a thesis in the Internet-measurement domain
