Summary

Leonhard Kurz Stiftung & Co. KG

Germany · AI-generated

business manufacturing corporate

LEONHARD-KURZ-STIFTUNG is operated by Leonhard Kurz Stiftung & Co. KG.

What it's used for

  • The address space carries corporate infrastructure for a global leader in thin-film technology and surface finishing, as indicated by the netname NET-LEONHARD-KURZ and the registrant identity.
  • The AS announces a single IPv4 prefix, 193.105.247.0/24, comprising 256 addresses, with 2 observed neighbours. This small inventory against a low neighbour count indicates an internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers, internal systems, and web/API endpoints supporting the company's manufacturing and administrative operations across its international locations.

Notable

  • The registrant LEONHARD KURZ STIFTUNG & CO. KG matches the AS handle and the announced prefix, confirming consistent ownership.
  • The address inventory consists of a single /24 block, which is typical for a corporate network requiring a dedicated, manageable range for internal segmentation and site connectivity.

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: 454 networks and 1,847 prefixes, as published 2026-11-11. 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.
