About this network

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.
