Summary

Comune di Brescia

Italy · AI-generated

government municipal italy

COMBS-AS is operated by Comune di Brescia, the municipal government of Brescia, Italy.

What it's used for

  • The address space carries municipal network infrastructure, as indicated by the netname COMBS-NET and registrant COMUNE DI BRESCIA across all announced prefixes.
  • The AS announces 1024 IPv4 addresses across 3 prefixes with 2 observed neighbours, a ratio consistent with a small, self-contained internal network rather than a transit or large access provider.
  • Traffic from this AS consists of internal municipal services, administrative systems, and public-facing web endpoints for the city of Brescia.

Notable

  • All three announced prefixes share the same netname COMBS-NET and registrant COMUNE DI BRESCIA, confirming a single, unified municipal estate.
  • The address inventory is compact and contiguous, comprising one /23 and two /24s within the 91.192.124.0/22 range, typical of a single-site or small multi-site government deployment.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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 1,773 prefixes, as published 2026-10-13. 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.
