Summary

CSN-Solutions GmbH

Germany · AI-generated

hosting datacenter transit

CSN-DATACENTERS is operated by CSN-Solutions GmbH.

What it's used for

  • The address space carries datacenter and cloud infrastructure, evidenced by netnames such as DE-CLOUDIAX-20180821, DE-SOLUTIONIT-20190103, and DE-CSN-DC-20140808, as well as reverse DNS entries like ip-85-202-89-0.cloudiax.com and fixed-ip-185-66-176-128.csn-solutions.net.
  • The AS announces 4096 IPv4 addresses across 9 prefixes and 3 IPv6 prefixes, while maintaining 112 observed neighbours; this high neighbour-to-address ratio indicates a transit or peering-heavy role rather than a large access network.
  • Traffic from this AS consists of datacenter workloads, cloud services, and hosted infrastructure for third-party providers like Cloudiax AG and solutionIT GmbH.

Notable

  • Registrants vary across the inventory, including Cloudiax AG, solutionIT GmbH, GHOSTnet GmbH, and Moritz Moeller Workstations, alongside the primary holder Stephan Rakowski, trading as CSN-Solutions GmbH.
  • The address inventory is a mix of /22, /23, and /24 blocks, with some prefixes registered to distinct entities, suggesting a model of hosting or leasing space to other operators.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
