Summary
Wien Energie
utility business telecom corporate
AT-WZN-AS is operated by Wien Energie GmbH, the municipal energy and telecommunications provider for Vienna.
What it's used for
- The address space carries corporate and utility infrastructure, evidenced by netnames like
AT-WZN-20020717and registrants explicitly listing "Wien Energie GmbH". - The AS announces 12,032 IPv4 addresses and 16 IPv6 prefixes, maintaining 32 observed neighbours; this ratio indicates a business network with moderate peering rather than a large-scale residential access provider.
Notable
- Registrants for the largest prefixes (213.143.96.0/19, 31.12.0.0/21, 185.106.108.0/22) align with the announcer, while three /24 blocks (83.229.64.0/24, 83.229.93.0/24, 83.229.109.0/24) are registered to Next Layer Telekommunikationsdienstleistungs- und Beratungs GmbH.
- The inventory consists of six IPv4 prefixes and ten IPv6 prefixes, showing a mix of legacy and modern address space allocation for the utility's operations.

Reputation
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: 436 networks and 1,769 prefixes, as published 2026-10-13. 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.
