    Asking google for a randomly selected common IP address from the 
    list, I found 
    <http://my.maceast.com/homevision-u-l/ace-l/linux-router-l/%2330765452>, 
    where Nicolas Riendeau reports a similar scan which happened on 
    April 13, 2001.
    
    Taking his log file entries ("MrShield") into account, the table of 
    attackers' IP addresses looks like this now:
    
    140.239.176.162 	keith	sobolev	tifa	mrshield
    165.121.70.75 		keith
    194.205.125.26 		keith	sobolev	tifa	mrshield
    194.213.64.150 		keith	sobolev	tifa	mrshield
    202.139.133.129 	keith	sobolev	tifa	mrshield
    203.194.166.182 	keith	sobolev	tifa	mrshield
    203.208.128.70 		keith	sobolev	tifa	mrshield
    207.55.138.206 		keith	sobolev	tifa
    208.184.162.71 		keith	sobolev	tifa	mrshield
    209.249.97.40 		keith	sobolev	tifa	mrshield
    212.23.225.98 		keith	sobolev	tifa	mrshield
    212.78.160.237 		keith		tifa	mrshield
    212.78.164.193 			sobolev
    216.220.39.42 		keith	sobolev	tifa	mrshield
    216.33.35.214 		keith	sobolev	tifa	mrshield
    216.34.68.2 		keith	sobolev	tifa	mrshield
    216.35.167.58 		keith	sobolev	tifa
    62.23.80.2 		keith	sobolev	tifa	mrshield
    62.26.119.34 		keith	sobolev	tifa	mrshield
    63.209.147.246 		keith	sobolev	tifa	mrshield
    64.14.200.154 		keith	sobolev	tifa
    64.37.200.46 		keith	sobolev	tifa	mrshield
    64.56.174.186 		keith	sobolev	tifa	mrshield
    64.78.235.14 		keith	sobolev	tifa
    
    Maybe what we are seeing here are mostly decoy addresses used by 
    some tool with an extremely bad RNG?
