Summary
OpenXS GmbH
isp enterprise legacy
OPENXS-AS is OpenXS GmbH, an internet and IT services provider in Flensburg on Germany's Baltic coast, serving businesses and public bodies in the region.
What it's used for
- Business internet access and connectivity for local organisations — the network's published downstreams include regional companies and the city administration of Flensburg.
- Managed IT and network services delivered on top of that connectivity.
Notable
- Small footprint (about 1,000 IPv4 addresses) but a real multihomed network: multiple upstream carriers and peering at the Hamburg exchanges.
- The customer mix is corporate rather than residential, so the address space behaves like business space: offices, servers, and site-to-site links.
Interesting
- Germany has an unusually deep bench of small regional ISPs like this one, kept viable by cheap peering at DE-CIX and a local customer base that prefers a provider it can phone.

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 1,771 prefixes, as published 2026-10-15. 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.
