I was curious what it was because of 'SRC=0.0.0.0'. It turned out to
be my Wii. I discovered this based on my router which keeps track of
MAC addresses and IP addresses. I had forgotten that it was on my
net.
This is a standard DHCP/BOOTP packet. When a system is booting up it
doesn't have an IP address to stick in there so it puts 0.0.0.0. The
DHCP server and/or DHCP relay uses the MAC address of the client to
send a response back.
