Summary

Flughafen Wien

Austria · AI-generated

airport corporate business infrastructure

The AS handle VIE-AS is operated by Flughafen Wien Aktiengesellschaft.

What it's used for

  • The address space carries internal corporate infrastructure for Vienna International Airport, evidenced by netnames such as AT-VIENNAAIRPORT-20190307, AT-VIENNAAIRPORT-20191008, and VIE-AT-PI-NET.
  • The AS announces 2816 IPv4 addresses across 7 prefixes and 2 IPv6 prefixes, with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • Registrants for most prefixes are listed as "IT Operations; Flughafen Wien Aktiengesellschaft", while two prefixes (83.68.143.0/24 and 83.68.146.0/24) are registered to "NOC Next Layer", suggesting leased or historically managed space.
  • The address inventory is finely subdivided into multiple /24 and /23 blocks, consistent with site-by-site segmentation within a single corporate estate.

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.
