    Anyone have any idea what might cause this:

    194.72.6.103:43697 255.255.255.255:19 L=28 S=0x00 I=1 F=0x0000 T=234 (#1)
    
    I have more (~13KB) at http://www.lib.uaa.alaska.edu/~tibor/broadcast.txt.
    
    I started seeing this stuff at about 02:30 this morning, and it lasted
    roughly 12 hours.  There were 5 unique source addresses: one from
    sprintlink.net, two in Germany, and one from Italy, however all of the
    packets show a TTL of 234.  Would this indicate the source addresses were
    likely spoofed, and the computer generating the traffic is relatively
    close (within a few hops)?
    
    I would greatly appreciate any hints or pointers anyone can give me.
    
    Thanks,
    Mike
