Summary

Stadtwerke Meerane GmbH

Germany · AI-generated

utility municipal germany

SWM is operated by Stadtwerke Meerane GmbH.

What it's used for

  • The address space carries municipal utility infrastructure, as indicated by the netnames DE-STADTWERKE-MEERANE-19930901 and DE-STADTWERKE-MEERANE-20200110 registered to Stadtwerke Meerane GmbH.
  • The AS announces 1280 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of internal corporate and municipal utility operations, including gas, electrical, and heating services for the town of Meerane.

Notable

  • All registrants for the announced prefixes are consistent with the AS holder, listing Stadtwerke Meerane GmbH as the administrator.
  • The address inventory is small and finely subdivided into three distinct IPv4 blocks, reflecting a segmented internal corporate estate for a local utility provider.

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 1,851 prefixes, as published 2026-11-03. 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.
