Summary

Die Netz-Werker

Germany · AI-generated

business it-services germany

HSPEED-AS is operated by Die Netz-Werker Systemmanagement und Datennetze AG.

What it's used for

  • The address space carries business and IT infrastructure traffic, evidenced by reverse DNS entries like web238-254.hspeed.net and web130-254.hspeed.net.
  • With 3072 IPv4 addresses announced across 3 prefixes and 10 observed neighbours, the ratio suggests a regional business or IT services provider rather than a large-scale transit or residential access network.

Notable

  • Registrants for two of the three announced prefixes (193.24.236.0/22 and 194.147.128.0/22) are explicitly listed as Die Netz-Werker, while the third (45.91.212.0/22) is registered to CeCon Computer Systems Handelsgesellschaft mbH.
  • The operator is identified in secondary sources as a nationwide IT system house (IT-Systemhaus) based in Berlin, formerly associated with Insoft EDV-Systeme.
  • The inventory consists of three /22 IPv4 blocks and a single /29 IPv6 prefix, indicating a modest, segmented address estate typical of a corporate or service provider environment.

Reputation

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
