About this network

GVS-AS is terranets bw GmbH, a Stuttgart-based gas transmission system operator for Baden-Württemberg. The handle preserves the company's former name, Gasversorgung Süddeutschland (GVS).

What it's used for

• Alongside its gas grid, terranets bw operates a fibre-optic network laid largely within the protective strips of its pipeline right-of-way, and sells telecommunications and dark-fibre services on it. This AS carries that network.
• Backbone routers in the bbl.tn-bw.de zone (e.g. dist01-bbl-stg in Stuttgart) confirm the operator's own infrastructure rather than a hosting or eyeball footprint.
• The AS also originates address space registered to regional business customers, so it acts as a connectivity provider to enterprises as well as carrying the utility's internal network.

Notable

• A utility with a telecom arm is an easy kind to get wrong. This is not a broadband ISP: there are no subscriber pools, and rDNS is sparse and infrastructure-shaped.
• Registry remarks list only the company's Stuttgart street address (Am Wallgraben 135), which is a postal address, not a business unit.
