Summary

Fraunhofer SIT

Germany · AI-generated

research business germany

FHI-SIT is the autonomous system for Fraunhofer SIT, the Information Security Technology research institute of the Fraunhofer-Gesellschaft.

What it's used for

  • The space carries internal research infrastructure, evidenced by the reverse DNS record ppc-lama2.sit.fraunhofer.de and the netname FHG-STUTTGART.
  • With 65,792 IPv4 addresses announced across 2 prefixes and only 1 observed neighbour, the inventory functions as a self-contained internal estate for the institute's operations rather than a transit or access network.

Notable

  • Registrants align with the announcer, including Fraunhofer Netzzentrum and Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V. for the smaller prefix, while the larger block is registered to IRT-DFN-CERT under the netname GMDDA-DE.
  • The address inventory consists of one large /16 block and one /24 block, reflecting a consolidated corporate allocation for the Stuttgart-based research facility.

Internet exchanges

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
