Summary

Services Industriels de Geneve

Switzerland · AI-generated

utility municipal telecom switzerland

SIG-DSI is the autonomous system for Services Industriels de Geneve.

What it's used for

  • The space carries internal corporate and utility infrastructure, identified by the netname SIG-SE-001 and registrant Services Industriels de Geneve.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix with only 1 observed neighbour, indicating a small, isolated internal network rather than a transit or access provider.
  • Traffic consists of internal communications for the municipal utility's operations, including its telecommunications service (SIG - Service Telecom).

Notable

  • The registrant Services Industriels de Geneve matches the AS holder, confirming consistent ownership.
  • The address inventory is minimal, consisting of a single /24 block and a single /48 IPv6 prefix, typical for a dedicated corporate 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: 442 networks and 1,771 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.
