Summary

FAS Vermietungs- und Beteiligungs-GmbH

Austria · AI-generated

business austria small

The AS handle ASFASNET is held by FAS Vermietungs- und Beteiligungs-GmbH.

What it's used for

  • The address space carries corporate infrastructure, indicated by the netname AT-FASVERMIETUNG-20191119 and reverse DNS entries pointing to asecc.at.
  • The AS announces 1024 IPv4 addresses across 4 prefixes with only 1 observed neighbour, a ratio consistent with a small, self-contained business network rather than a transit or large access provider.
  • Traffic from this AS consists of internal corporate endpoints for the company's operations in Studenzen, Austria.

Notable

  • All registrants for the announced prefixes are Fuchs Guenter; FAS Vermietungs- und Beteiligungs-GmbH, which aligns perfectly with the AS holder.
  • The address inventory consists of four non-contiguous /24 blocks within the 193.228.0.0/16 range, all registered under the same netname.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
