Summary

Knipp Medien und Kommunikation GmbH

Germany · AI-generated

business dns media germany

KNIPP-IRONDNS1-AS is operated by Knipp Medien und Kommunikation GmbH.

What it's used for

  • The address space carries infrastructure for a media and communication company, with netnames explicitly referencing ironDNS (e.g., ironDNS-NG2, ironDNS-NET4) and specific site identifiers like KNIPP-SIN and KNIPP-MIA.
  • The AS announces 5120 IPv4 addresses across 11 prefixes and 11 IPv6 prefixes, while maintaining only 2 observed routing neighbours. This high address-to-neighbour ratio indicates an internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal corporate endpoints, DNS infrastructure, and media production or distribution services associated with the Knipp group.

Notable

  • Registrants are consistent with the announcer, with most prefixes registered to Knipp Hostmaster or Knipp Medien und Kommunikation GmbH; the prefix 185.95.96.0/22 is registered to Variomedia AG.
  • The inventory is finely subdivided into multiple /23 and /24 blocks, reflecting site-by-site segmentation within the corporate network.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,773 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.
