About this network

The RIR handle reads "ATOS IT Solutions and Services", but the current organisation object is Eviden Austria GmbH — the Austrian arm of Atos's Eviden division. Its registered address is Siemensstrasse 92 in Vienna, and its contacts still carry Siemens AG affiliations.

What it's used for

• Outsourced and managed IT. Around 2,000 IPv4 addresses across seven small prefixes carrying customer systems that Eviden runs on their behalf. The rDNS is a roll-call of client estates rather than one company: services.siemens.at, pat-a4b.siemens.at, fw-sie-andritz1-1.siemens.at, remedy.nsn.com, webdispatcher1.nlmk.admingate.local, test-go.energylink.at.
• The recurring admingate.net / admingate.local domain is the outsourcer's own management gateway naming, applied across otherwise unrelated customers — the tell that one operator is running all of them.

Notable

• Classify by what the space carries, not by the customer names in the rDNS. Seeing siemens.at or nlmk here does not mean the addresses belong to Siemens or NLMK; they are managed estates inside an IT-services provider's blocks. Only 194.138.12.0/24 is genuinely Siemens-registered (DE-SIEMENS-19950123), routed here by arrangement.
• The prefixes are a mix of PI, PA and legacy space still labelled ATOS-NET, ATOS CEE, EARNE-AT and ADMINGATE-NET, reflecting layers of corporate history: Siemens IT Solutions and Services became part of Atos, and Atos later spun the business into Eviden.

Interesting

• The Vienna street address is Siemensstrasse — the company moved out of Siemens' ownership but not out of its building.
