Summary

Xenox IT & Kommunikations GmbH

Austria · AI-generated

business austria small

The AS handle ROUBICEK-AS is held by Xenox IT & Kommunikations GmbH.

What it's used for

  • The address space carries business traffic, evidenced by the netname AT-XENOX-20020204 and reverse DNS entries pointing to mmc.at.
  • The network announces 256 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, isolated business or corporate site rather than a transit or large access provider.
  • Traffic from this AS consists of internal corporate endpoints and services associated with the Xenox IT & Kommunikations GmbH infrastructure.

Notable

  • The RDAP registrant for the announced prefix is Xenox IT & Kommunikations GmbH, which aligns with the AS holder identity despite the AS handle referencing Peter Roubicek.
  • The inventory consists of a single /24 IPv4 block and a single /48 IPv6 block, representing a compact, self-contained address 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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
