AS6878 AS6878 - T-Systems International GmbH

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, where ecs is 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 80.158.0.0/16 and 164.30.0.0/16.

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.
