About this network

STW-AS is operated by Stadtwerke Klagenfurt AG, a municipal utility and regional internet service provider in Austria.

What it's used for

• The address space carries infrastructure for a local utility and its associated services, with netnames referencing CITYWEB-SECURED, RAIFFEISEN-STW-NET, and monitoring tools like SMOKEPING.
• The AS announces 11,008 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, while maintaining only 2 observed neighbours, a ratio that indicates a small, self-contained access or internal corporate network rather than a transit provider.

Notable

• All RDAP registrants consistently identify Stadtwerke Klagenfurt AG or STW NOC, aligning perfectly with the AS holder.
• The inventory consists of a mix of older blocks dating back to 1993 and 1995, alongside more recent allocations, reflecting the long-standing operational history of the municipal entity.
