Summary
Achermann ict-services AG
business it-services switzerland
ACAG-AS is operated by Achermann ict-services AG.
What it's used for
- The address space carries corporate infrastructure, evidenced by reverse DNS entries pointing to
achermann.chand netnamesCH-ACAG-20121001andACAG-IPV4-NET. - The AS announces 1536 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.
- Traffic from this AS consists of internal IT services, cloud infrastructure, and managed services endpoints for Achermann's clients and internal operations.
Notable
- Registrants for both announced prefixes are listed as Achermann ict-services AG, consistent with the AS holder.
- Achermann ict-services AG is a Swiss IT services company based in Kriens, providing ICT consulting, cloud, and managed services.
- The inventory is finely subdivided into two distinct IPv4 blocks and one IPv6 block, typical of a corporate network segmented by function or site.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,779 prefixes, as published 2026-10-21. 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.
