About this vendor.
A MAC address beginning with 00:E6:D3 or 02:E6:D3 identifies hardware registered to NIXDORF COMPUTER CORP., the US subsidiary of the West German computer company Nixdorf Computer AG.
The registrant is a defunct entity that dissolved in 1990. It merged with Siemens to form Siemens Nixdorf Informationssysteme AG, which later split into Fujitsu Siemens Computers and Wincor Nixdorf. The company operated in the computer industry, focusing on mainframe and banking/point-of-sale systems.
No live official website exists for this defunct entity, so no current operator or product line can be confirmed. The specific device types associated with these prefixes are not established in the available sources.
The registrant is not listed in the CISA Known Exploited Vulnerabilities Catalog (catalog 2026.09.23, 1721 entries). IEEE publishes no registration or assignment date for these prefixes, and no third-party lookup consulted carried one either.
