About this network

The AS handle ZF-FRIEDRICHSHAFEN-AG is held by ZF Friedrichshafen AG.

What it's used for

• The address space carries corporate infrastructure for ZF, a global automotive supplier, with netnames such as de-zffriedrichshafen, ZF-TRW-UK, and ZF-FN indicating site-specific or regional subdivisions.
• The AS announces 221,184 IPv4 addresses across 39 prefixes and 2 IPv6 prefixes, while maintaining only 3 observed routing neighbours; this high address-to-neighbour ratio indicates an internal corporate estate with site-by-site segmentation rather than an access or transit network.
• Traffic from this AS consists of office workers, engineering systems, and internal corporate endpoints for ZF's global operations.

Notable

• All registrants in the evidence pack are consistent with the announcer, listing "ZF Friedrichshafen AG; ZF ISP-Team; Abuse-C Role" for every sampled prefix.
• The address inventory is finely subdivided into numerous /21, /22, and /23 blocks, reflecting a structured internal network design for a large multinational corporation.
