Education RIPE
Summary
Fraunhofer IESE (Fraunhofer-Gesellschaft)
education research legacy
AS9020-FRAUNHOFER-IESE-KL belongs to the Fraunhofer-Gesellschaft, Germany's largest applied-research organisation, and specifically to the Fraunhofer Institute for Experimental Software Engineering (IESE) in Kaiserslautern.
What it's used for
Networking for a research institute. It announces two small prefixes (153.96.133.0/24 and 153.96.134.0/23) with one observed neighbour. Sampled reverse DNS resolves to drNNN.iese.fraunhofer.de, i.e. the institute's own hosts, confirming this is Fraunhofer IESE's site network rather than a provider.
Notable
A tiny, contiguous, single-upstream footprint (~768 addresses) that has been in BGP since at least 2000, consistent with an early academic/research allocation.
Interesting
Fraunhofer IESE is a well-known applied-research centre in software and systems engineering, so the AS carries an R&D campus rather than commercial services.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-05, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Education University, school or national research and education network.
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: 453 networks and 1,854 prefixes, as published 2026-11-06. 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.
