Ho ho… Whenever in doubt, download Colasoft’s Packet Builder, and toss those HEX values into a fresh packet. It’ll show you all the information you need, right down to a tee.
Mind you, just at first glance…
Sender Mac Address: FF FF FF FF FF FF
Destination Mac Address: 00 D0 2B 75 3D 8C
And then the listed Sender/Dest Mac Addr placed in the next portion is:
Sender Mac Address: 00 D0 2B 75 3D 8C
Destination Mac Address: 00 00 00 00 00 00
Hope this answers your question.
The broadcast MAC address will never be the source address on any IP traffic. This is malicious traffic if the source is broadcast. The destination address for ARP requests will be all 00′s as shown above.
This does not look like a valid ARP request packet. A valid ARP request would start out with
00 01 08 00 06 04 00 01
