AS9020 — AS9020-FRAUNHOFER-IESE-KL Fraunhofer IESE Institut Experimentelles Software Engineering

Network type: education

AS9020 announces 2 IPv4 prefixes covering 768 addresses and 1 IPv6 prefixes.

About this network

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.
