Summary

ratiokontakt

Germany · AI-generated

hosting cloud legacy

ratiokontakt GmbH (ratiokontakt) — a managed-hosting and cloud provider from Bamberg, Germany, providing internet services since 1996 and running its own data centre in Nuremberg. Around 74,000 IPv4 addresses, dominated by a legacy 212.223.0.0/16, plus two IPv6 /32s.

What it's used for

  • Managed servers, shared and dedicated hosting, email, domains and private/hybrid cloud for German business customers. Tens of thousands of hosted domains sit behind the space.
  • The rDNS shows the operator's own core (ecore.net — a ratiokontakt brand, including its Frankfurt core routers and customer account portal) alongside hosted customer sites and remote-access gateways for managed-IT clients.

Notable

  • A /16 is a large block for a company this size, and it is a legacy allocation: the netname records a 1998 registration, from the era when a German ISP could still ask for a Class B. Most of it carries no reverse DNS.
  • Peering is at DE-CIX and the Nuremberg exchange with an open policy, but the AS has only a handful of transit neighbours — a content/hosting network's shape, not a carrier's.

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: 436 networks and 1,771 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.
