About this network

The AS handle AS-DBNETZ is held by DB InfraGO AG.

What it's used for

• The address space carries internal corporate infrastructure for Germany's railway network, evidenced by netnames DE-DBNETZ-20131001, DE-DBINFRAGO-20250701, and DE-DBINFRAGO-20241112 all registered to DB InfraGO AG.
• With 1024 IPv4 addresses announced across 3 prefixes and only 2 observed neighbours, the inventory represents a finely subdivided internal corporate estate rather than a transit or access network.

Notable

• Registrants for all announced prefixes are consistent with the announcer, listing DB InfraGO AG or DB Netz abuse.
• DB InfraGO AG was created on 27 December 2023 through the merger of DB Netz AG and DB Station&Service AG, operating as a wholly owned subsidiary of Deutsche Bahn.
• The address inventory consists of three contiguous IPv4 prefixes in the 185.36.136.0/23 range and a single IPv6 prefix, reflecting a compact, site-segmented corporate allocation.
