Unclassified RIPE
Summary
Hessische Zentrale für Datenverarbeitung
government data hessian network
The AS handle HZD-AS is held by Hessische Zentrale für Datenverarbeitung.
What it's used for
- The address space carries the operational network of the Hessian state data processing center, with all registrant netnames identified as
HZD-NET. - The inventory consists of 16 IPv4 prefixes and 1 IPv6 prefix, with 16640 IPv4 addresses announced against only 2 observed neighbours, indicating a self-contained internal corporate estate rather than a transit or access network.
Notable
- All RDAP registrants for the largest prefixes agree with the announcer, consistently listing
Hessische Zentrale fuer Datenverarbeitungas the registrant. - The address inventory is finely subdivided into 16 distinct IPv4 prefixes within the 141.90.0.0/16 range, reflecting site-by-site segmentation typical of a large internal government infrastructure.

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 2026-10-14, 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 1,771 prefixes, as published 2026-10-15. 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.
