The naming scheme for wanadoo domains is
A`location name`-x-y-z-t.abo.wanadoo.fr
where x seems to be a three digit name (I don't know what it mean)
      y seems to be a one digit name (i've never seen other than 1)
      z seems to be the number of the class C used for this location
      t seems to be the last IP number
location is a city name, except for Paris where it is divided in regions
of the town.

What I want to say is that the attacks seem to come from very different
places in France. It may be a very well coordinated large scale crackers
group. But it's far more probable that the attacks come from compromised
machines or from spoofed IPs, and that the attacker don't like wanadoo.
