Summary

ROWANet

Czechia · AI-generated

government backbone regional czechia

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.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-17. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
