Summary

Switzerland · AI-generated

municipal cable energy telecom

SIL-CITYCABLE-AS is operated by Services Industriels de Lausanne (SIL).

What it's used for

  • The address space carries municipal utility and telecommunications infrastructure, evidenced by netnames CH-SIMA-LAUSANNE-20050125 and CH-SIMA-LAUSANNE-20140723 registered to SIL, and VILLE-DE-LAUSANNE registered to the Service d'organisation et d'informatique.
  • The AS announces 34048 IPv4 addresses across 3 prefixes with 3 observed neighbours, a ratio consistent with a local access or municipal network rather than a transit provider.

Notable

  • Registrants align with the announcer for the two largest prefixes, both held by Services Industriels de Lausanne, while the smallest prefix is held by the City of Lausanne's IT service.
  • SIL is a municipal utility agency in Lausanne providing energy, water, and telecommunications services, including the Citycable broadband brand.
  • The inventory consists of three distinct IPv4 blocks with no IPv6 prefixes announced.

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 1,772 prefixes, as published 2026-10-15. 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.
