Summary

InfraLeuna GmbH

Germany · AI-generated

business industrial infrastructure corporate

LEUCOM-AS is operated by InfraLeuna GmbH.

What it's used for

  • The address space carries internal corporate infrastructure for the Leuna chemical site, evidenced by the reverse DNS record int254.leucom.de and netnames such as DE-LEUCOM-GMBH-20111118 and NET-LEUCOM-ENVIATEL.
  • The AS announces 4352 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining only 4 observed neighbours, a ratio indicative of an internal corporate estate rather than a public access or transit network.

Notable

  • Registrants for the primary prefixes are consistently InfraLeuna GmbH, aligning with the AS holder, though the smallest prefix 153.97.148.0/24 is registered to FHG LIR ROLE under the netname FHG-CBP.
  • The address inventory is finely subdivided into four distinct IPv4 blocks, reflecting site-by-site segmentation typical of a large industrial facility managing its own internal network.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,781 prefixes, as published 2026-10-16. 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.
