Hi,

ARP messages are 28 bytes long. Ethernet requires 64 octets on the wire, hence a 
trailer is applied.
Why don't you see the trailer on the ARP requests your hosts sends out? That is 
probably because the trailer is appended after the frame has passed through the 
capture layer. On the incoming ARP reply you see it because it's coming from the 
wire.

Thanx,
Jaap
