Hosting RIPE
Summary
T-Systems International (Open Telekom Cloud)
hosting cloud legacy
AS6878 is held by T-Systems International GmbH, Deutsche Telekom's enterprise IT and systems-integration arm. In practice the address space behind it carries Deutsche Telekom's public cloud.
What it's used for
- Public-cloud compute and infrastructure-as-a-service. Reverse DNS across the announced prefixes resolves as
ecs-80-158-2-1.reverse.open-telekom-cloud.com, whereecsis the platform's Elastic Cloud Server product, so these are customer virtual machines rather than corporate desktops. - The platform is marketed as a sovereign European public cloud with data held in German data centres.
Notable
- This is a cloud host, not a carrier network, even though the abuse contact points at Deutsche Telekom's LIR desk and the administrative contact sits in Deutsche Telekom IT GmbH. The parent group is a telco; this particular AS is not the telco's eyeball or backbone network.
- Roughly 42k IPv4 addresses plus IPv6, largely inside
80.158.0.0/16and164.30.0.0/16.
Interesting
- The Open Telekom Cloud brand has since been folded into Deutsche Telekom's "T Cloud Public" naming, but the reverse DNS still carries the original name, which makes the AS easy to identify from a traceroute alone.

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
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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.
