German trains show Kernel, IP-address *and* MAC address

  • IP:
  • MAC: 74:38:89:00:66:C9

The MAC address indicates the network device is made by ANNAX Anzeigesysteme GmbH.

Writing tests for http / https request: Postman, SoapUI, Advanced REST client.

You can get both Postman versions through as well.
