Summary
Knipp Medien und Kommunikation GmbH
hosting dns legacy
KNIPPWORLDWIDE belongs to Knipp Medien und Kommunikation GmbH, a Dortmund company that operates domain-name infrastructure: the TANGO Registry Services platform used to run top-level domains (including brand TLDs such as .sap and .bauhaus), an ICANN-accredited registrar business, and ironDNS, its own unicast/anycast nameserver network deployed across roughly ten sites worldwide.
What it's used for
Authoritative DNS and registry back-end services. The routing shape is unusual and tells the story: about 7,680 IPv4 addresses across 21 prefixes, but 20 IPv6 prefixes — a lot of separate announcements for a small operator, which is what an anycast nameserver estate looks like when each node needs its own routable slice.
The sampled reverse DNS confirms it: anycast96.irondns.net is a nameserver node, while ip1-120-253-195.knipp.de and ip0.89.253.195.irondns.knipp.de are the company's own generated host records. There is no subscriber space and no third-party tenancy on the addresses sampled.
Notable
- Do not geolocate the anycast prefixes to Dortmund. By design, the same addresses answer from multiple continents; the company's registered address says nothing about where a given packet lands.
- DNS registry operators sit awkwardly in any usage taxonomy — the space is server infrastructure, but of a kind that serves the naming system itself rather than tenant workloads.

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 2026-10-13, 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 1,773 prefixes, as published 2026-10-13. 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.
