AS2117 Garching, Germany
Unclassified RIPE
Summary
European Southern Observatory (ESO)
research legacy
The European Southern Observatory, an intergovernmental astronomy organisation headquartered in Garching bei München, Germany.
What it's used for
- Networking for ESO's headquarters and its research and data operations supporting telescopes in Chile.
Notable
- A scientific research organisation, not a commercial provider; its upstream is Germany's research network DFN (AS680).
Interesting
- The allocation dates to 1993, and the "Garching, Germany" clue points to ESO's campus there, not the neighbouring Max Planck computing centre.

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.
