Summary

IT.NRW

Germany · AI-generated

government infrastructure state it

IT-NRW is operated by Information und Technik Nordrhein-Westfalen (IT.NRW), the state IT agency for North Rhine-Westphalia.

What it's used for

  • The address space carries internal government IT infrastructure, evidenced by the netname DE-IT-NRW-20080527 and registrant Service-Desk IT.NRW; Information und Technik Nordrhein-Westfalen.
  • The AS announces 4096 IPv4 addresses in a single /20 prefix and 3 IPv6 /48 prefixes, with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal administrative systems, statistical databases, and IT services supporting the North Rhine-Westphalia state government.

Notable

  • The registrant Service-Desk IT.NRW; Information und Technik Nordrhein-Westfalen aligns directly with the AS holder, confirming consistent ownership.
  • The address inventory is compact and finely subdivided into one IPv4 block and three IPv6 blocks, typical of a corporate or governmental estate 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 2026-10-14, 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 1,772 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.
