Hewlett Packard Enterprise

Any device whose MAC address begins with EC:33:CC has a network interface built by Hewlett Packard Enterprise. This prefix (the OUI, or Organizationally Unique Identifier) is assigned by the IEEE and is the first three octets of the address — it covers every MAC from EC:33:CC:00:00:00 to EC:33:CC:FF:FF:FF.
