Summary
Hertener Stadtwerke GmbH
utility municipal business germany
ASHSW is the autonomous system for Hertener Stadtwerke GmbH, a municipal utility provider in Herten, Germany.
What it's used for
- The address space is registered under the netname
DE-HSW-20050627with registrants listed as "Netmaster Hertener Stadtwerke" and "Hertener Stadtwerke GmbH". - The AS announces 2048 IPv4 addresses across 3 prefixes in Germany, while maintaining only 2 observed neighbours. This low neighbour count relative to the address inventory indicates an internal corporate estate rather than a transit or access network.
Notable
- All three announced prefixes share the same registrant and netname, confirming a consistent ownership structure aligned with the AS holder.
- The address inventory consists of three contiguous IPv4 blocks: 85.119.212.0/22, 85.119.208.0/23, and 85.119.210.0/23.
- The operator has been visible in routing tables since 2005-07-13.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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 1,784 prefixes, as published 2026-10-19. 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.
