Summary

ACP IT Solutions

Austria · AI-generated

business it-services austria

ACP-AT-AS is operated by ACP IT Solutions GmbH.

What it's used for

  • The address space carries corporate IT infrastructure, evidenced by netnames AT-ACPITAS-20140227 and ACP-AT-NET, and reverse DNS entries such as dmz.acp.at and rev.nessus.at.
  • The AS announces 768 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints, DMZ services, and IT management systems for ACP's client-facing digital transformation and hybrid cloud solutions.

Notable

  • Registrants for both prefixes are ACP IT Solutions GmbH, aligning perfectly with the AS holder.
  • ACP IT Solutions GmbH is a manufacturer-independent IT provider in Austria, offering end-to-end solutions for companies, authorities, and organisations, with offices in Salzburg, Gmunden, Vienna, and St. Pölten.
  • The inventory is compact, consisting of one /23 and one /24 block, typical for a mid-sized enterprise managing its own IP space for internal and client-facing services.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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: 442 networks and 1,773 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.
