Motivation
Internet measurements have long been a research priority at our chair. These measurements help us better understand the Internet and its security.
Over the years, we acquired vast knowledge in the area of large scale network measurements. This helps us to understand the current network state and its development. We seek to be harmless and conduct all measurements in an ethical manner.
If you are an interested researcher or students who wants to cooperate with us or if you have any questions, feel free to contact us. GINO is a research group for exchanging ongoing research, concepts, and ideas in the Internet measurement domain.
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.
Futher information can be found on Scans.
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.
Toplists
We provide a daiy-to-day analysis of regularly used toplists. Find more information on our github Toplist page.
SMB Scans
In cooperation with the Chair of IT Security, SMB scans to detect honeypots are conducted at our chair. Find more information on SMB Scans.
PTP Scans
From time to time, we execute PTP scans, searching for unicast capable PTP master clocks in the Internet. We send a UDP Request Unicast PTP probe to port 320. This probe request a unicast transmission with 1 packet per second for a duration of 1 second.
