Summary

ARD ZDF Deutschlandradio Beitragsservice

Germany · AI-generated

government media corporate

ZBS-AS is the autonomous system for ARD ZDF Deutschlandradio Beitragsservice.

What it's used for

  • The space carries internal corporate infrastructure for the German public broadcasting fee collection agency, identified by the netname DE-ZBS-NET.
  • The AS announces 512 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • Registrants for both announced prefixes match the announcer, listing ARD ZDF Deutschlandradio Beitragsservice as the holder.
  • The address inventory consists of two contiguous /24 blocks, 193.189.157.0/24 and 193.189.158.0/24, forming a compact and uniform estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,779 prefixes, as published 2026-10-21. 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.
