Summary

Swisscom (Schweiz) AG — Test-AS-Main

Switzerland · AI-generated

infrastructure legacy

Test-AS-Main is an auxiliary Autonomous System of Swisscom, the Swiss incumbent telecom operator. It is not a product or a customer-facing network: as the name says, it is a test AS, registered to Swisscom and maintained under the old CH-UNISOURCE-MNT object inherited from the Unisource era.

What it's used for

  • Announcing a small set of Swisscom backbone infrastructure prefixes. Every address sampled inside them resolves into bb.ip-plus.net, Swisscom's IP-Plus backbone: router interface names of the form SITE-NNN-INTERFACE.bb.ip-plus.net covering link and loopback addressing rather than anything a customer uses.
  • It sits behind Swisscom's main AS3303 and a second European upstream, and has no downstream customers of its own.

Notable

  • Infrastructure only. There is no subscriber, hosting or business-access space on this AS. Swisscom's consumer and enterprise networks are numbered elsewhere, and inheriting the incumbent's kind onto this AS number would be wrong: it belongs in no ordinary category.
  • Because the addresses are router interfaces, they carry backbone traffic but do not originate end-user activity. Geolocating or attributing behaviour to them as if they were subscriber addresses is a mistake.
  • The 193.5.x and 194.209.x ranges it announces are old Swiss classful-era blocks, consistent with a low AS number in a national incumbent's estate.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
