Summary

DC:MAIN GmbH

Germany · AI-generated

business germany small

DCMAIN-AS is operated by DC:MAIN GmbH, a German entity registered under the name of Dominik Schubert.

What it's used for

  • The address space carries business infrastructure, indicated by the netnames DCMAIN-NET and DE-SITG-20150203 associated with the announced prefixes.
  • The AS announces 768 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale business or internal network rather than a transit or large access provider.
  • Traffic from this AS consists of web and API endpoints for the DC:MAIN GmbH business operations.

Notable

  • Registrants for the largest prefixes are Abuse-C Role and Dominik Schubert, which align with the AS holder DCMAIN-AS Dominik Schubert.
  • The address inventory is small and finely subdivided into two IPv4 blocks, consistent with an internal corporate estate or small business deployment.

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: 447 networks and 1,852 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.
