Summary

Touring Club Suisse

Switzerland · AI-generated

business corporate switzerland

TCS is the autonomous system for Touring Club Suisse.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames such as CH-TCS-20180724, TCS-NET, and TCS-PUB-DP.
  • The AS announces 1280 IPv4 addresses across 4 prefixes with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of internal corporate communications, web endpoints, and administrative services for the organization's 1,900 employees and member-facing digital platforms.

Notable

  • Registrants for all announced prefixes list IP-Max Engineering and Touring Club Suisse, confirming the space is directly held by the organization.
  • The address inventory is finely subdivided into four distinct prefixes, consistent with site-by-site segmentation for a large corporate entity.
  • No IPv6 prefixes are currently announced in the inventory.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, 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 1,778 prefixes, as published 2026-10-20. 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.
