About this network

STWKUFSTEIN-AS is operated by Stadtwerke Kufstein GmbH, a municipal utility company in Kufstein, Austria.

What it's used for

• The address space carries residential and business internet access, evidenced by reverse DNS entries like 213-182-247-254.static.kufnet.at and netnames such as AT-STWKUFSTEIN-20030313.
• The AS announces 24064 IPv4 addresses across 16 prefixes and 20 IPv6 prefixes, while maintaining 111 observed neighbours; this ratio of moderate address space against a high neighbour count indicates a regional access provider rather than a transit carrier.

Notable

• All RDAP registrants for the largest prefixes are listed as Stadtwerke Kufstein GmbH, fully aligning with the AS holder.
• The address inventory is finely subdivided into multiple /22 and /23 blocks, consistent with an internal corporate estate serving a specific municipal area rather than a large-scale national ISP.
