Mysterious Raw Ethernet II Packets on Network Captures
I'm having a terrible time diagnosing why these Raw Ethernet II packets are on my network.  The destination MAC address seems to increment where the source MAC address seems random.  Possible IPv6?  Netgear equipment.  Thanks in advance for any assistance.
