Summary

Austro Control

Austria · AI-generated

government aviation infrastructure

AUSTROCONTROL-AS is operated by Austro Control, the Austrian air navigation services provider.

What it's used for

  • The address space carries internal corporate infrastructure, identified by netnames AT-AUSTROCONTROL-NET and ACG-PI-NETWORK.
  • The AS announces 8,960 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic consists of internal data for air traffic control systems, administrative functions, and aviation safety operations supporting Austrian airspace management.

Notable

  • Registrants are consistent with the announcer, listing Host Master Highway for most prefixes and Austro Control Oesterreichische Gesellschaft fuer Zivilluftfahrt mit beschraenkter Haftung for the ACG-PI-NETWORK block.
  • The address inventory is finely subdivided into six distinct IPv4 prefixes, reflecting site-by-site segmentation typical of a large internal corporate estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
