Summary

DDV Sachsen GmbH

Germany · AI-generated

media business corporate

DDV-AS is operated by DDV Sachsen GmbH.

What it's used for

  • The address space carries corporate web and print infrastructure, evidenced by reverse DNS entries such as www1-63.dd-v.de and prti-2-62.dd-v.de.
  • The network announces a single IPv4 prefix, 195.74.44.0/22, comprising 1024 addresses, with one observed neighbour, indicating a small, self-contained corporate estate rather than a transit or access network.
  • Traffic from this AS consists of web servers and print production endpoints for the DDV Media Group, which publishes regional newspapers and digital media in Saxony.

Notable

  • The registrant DDV Sachsen GmbH matches the AS holder, confirming direct ownership of the address space.
  • The inventory consists of a single contiguous /22 block, typical of a corporate network segmented for internal use.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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 1,781 prefixes, as published 2026-10-16. 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.
