Summary

mbk networks GmbH

Germany · AI-generated

business germany mbk

MBK-NETWORKS-AS is operated by mbk networks GmbH.

What it's used for

  • The address space carries corporate and commercial traffic, evidenced by netnames DE-MBK-NETWORKS-20100603, KG-LUDWIG-MELOSCH-GMBH-NET, and MBK-NET.
  • The AS announces 1536 IPv4 addresses across 3 prefixes with 2 observed neighbours, indicating a small-scale business network rather than a transit or large access provider.
  • Traffic consists of office and branch connectivity for the mbk networks entity and its associated commercial partners, specifically Ludwig Melosch GmbH & CO. KG.

Notable

  • Registrants align with the announcer, listing mbk networks hostmaster and mbk networks GmbH for the primary block, and Ludwig Melosch GmbH & CO. KG for the secondary blocks.
  • The address inventory is compact, consisting of one /22 and two /24 blocks, all located in Germany.

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 1,778 prefixes, as published 2026-10-20. 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.
