Summary

Hamburger Energienetze GmbH

Germany · AI-generated

utility municipal grid infrastructure

SNH-ASN1 is held by Hamburger Energienetze GmbH.

What it's used for

  • The address space carries utility grid infrastructure, evidenced by the netname DE-STROMNETZ-HAMBURG-20181019 and the registrant Hamburger Energienetze GmbH.
  • The AS announces 1024 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of control, monitoring, and backhaul traffic for the municipal gas, electricity, and hydrogen distribution networks in Hamburg.

Notable

  • The RDAP registrant Hamburger Energienetze GmbH matches the AS holder, confirming consistent ownership of the announced space.
  • Hamburger Energienetze GmbH was formed on 1 September 2024 as a joint venture between Stromnetz Hamburg GmbH and Gasnetz Hamburg GmbH, merging the city's municipal grid operators.
  • The inventory consists of a single /22 IPv4 block and a single /29 IPv6 prefix, representing a finely subdivided internal corporate estate for site-by-site segmentation.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-29, 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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
