About this network

ROWANET-AS is operated by Kraj Vysocina, the regional government of the Vysočina Region in the Czech Republic.

What it's used for

• The address space carries regional government infrastructure, evidenced by reverse DNS entries such as digitalizace.kr-vysocina.cz and BCT-216.93.195.kr-vysocina.cz, and netnames CZ-KRAJVYSOCINA-20160229 and CZ-ROWANET.
• The AS announces 1280 IPv4 addresses across 3 prefixes and 2 IPv6 prefixes, with only 2 observed neighbours, indicating a small, self-contained regional backbone rather than a transit or large-scale access network.
• Traffic consists of internal communications, digital services, and administrative endpoints for the Vysočina regional government and its affiliated institutions.

Notable

• Registrants for all announced prefixes are consistently listed as "Kraj Vysocina Network Admins" and "Kraj Vysocina", aligning directly with the AS holder.
• The address inventory is finely subdivided into three distinct IPv4 blocks, reflecting site-by-site or service-specific segmentation within the regional government's internal network.
