Summary

Ville et Eurometropole de Strasbourg

France · AI-generated

government municipal network

CUSTRASBOURG is operated by Ville et Eurometropole de Strasbourg.

What it's used for

  • The address space carries municipal network infrastructure, evidenced by the netname CUS-NET and reverse DNS entries pointing to rev.cus-strasbourg.net.
  • The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, indicating a small-scale internal network rather than a transit or large access provider.
  • Traffic consists of internal communications for the city of Strasbourg and the Eurometropolis, supporting municipal services and administrative operations.

Notable

  • The registrant Ville et Eurometropole de Strasbourg matches the AS holder, confirming direct ownership of the address space.
  • The inventory consists of a single /24 block, 195.130.207.0/24, which is finely managed for internal use.

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 1,782 prefixes, as published 2026-10-16. 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.
