business it-services austria

NETZWARE-AS is operated by Netzware Handels- und IT-Dienstleistungs GmbH.

What it's used for

  • The address space carries IT services and network technology infrastructure, with reverse DNS entries pointing to netzware.at and netnames including AT-NETZWARE-20060626 and AT-NETZWARE-20180322.
  • The AS announces 3328 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small-scale business or internal corporate estate rather than a transit or large access network.
  • Traffic from this AS consists of web/API endpoints and internal network services for an IT services and consulting firm specializing in network technology.

Notable

  • Registrants for the largest prefixes are Netzware Handels- und IT-Dienstleistungs GmbH, while 185.126.20.0/22 is registered to Video-Broadcast GmbH under netname AT-CYBERTRON-20151112, and 45.12.99.0/24 is registered to Abuse-C Role under netname Digitalnova01-Net.
  • The address inventory is finely subdivided into four distinct IPv4 blocks, suggesting site-by-site segmentation or leased space management within a corporate IT environment.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,771 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.
