Video: Local Area Network Addressing

In the Local Area Network Addressing video (part of How Networks Really Work webinar) I covered numerous obscure LAN addressing details including:

  • There’s no layer-2 address in Fibre Channel frames (because FC is routing not bridging);
  • Why is the multicast bit lowest bit (0x01) in first byte on Ethernet but highest bit (0x80) on Token Ring or FDDI;
  • How some NIC manufacturers never got the memo on what OUI really means.
You need Free ipSpace.net Subscription to watch the video, and the Standard ipSpace.net Subscription to register for upcoming live sessions.
