Summary
Knipp Medien und Kommunikation
hosting legacy
KNIPP-AS belongs to Knipp Medien und Kommunikation GmbH of Dortmund, a German company best known for building and running domain-registry and registrar systems. The AS carries Knipp's hosting and service platforms.
What it's used for
- Hosting and managed services for Knipp's customers. Reverse DNS is dense with per-customer service names under
knipp.de, including virtual-machine and platform hosts, and the naming shows separate customer estates rather than a single flat network. - Registry and DNS infrastructure. Knipp's business is the software and operations behind top-level-domain registries and registrar systems, so a good deal of what it announces is DNS-adjacent service platform.
Notable
- A hosting and services network, not an access provider. Roughly 50,000 IPv4 addresses, most of it three contiguous
/18s in195.253.0.0space, plus a set of/24s and an IPv6/32. Over a hundred BGP peers for a network this size, which suits a company running DNS services that want to be reachable everywhere. - Part of the space carries reverse DNS under
dokom21.de, the Dortmund regional carrier, so some of the addressing is shared with or delegated to that neighbouring network. Don't read every address in the AS as Knipp's own.
Interesting
- The kind of network that is invisible to end users but sits under things they use constantly. Registry back-end operators are a small club, and their networks are small, old, well-peered, and carry far more importance than their address count suggests.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
