<added>Oh and, welcome to WmW berno.</added>
I really like the host name of 184.108.40.206 ;-) devnull.ussc.alltheweb.com
This is all deja vu, because I was just going through my fast ip's earlier today. Basically for Fast ip's I have: 209.202.148.* 209.67.247.* 213.120.56.* 213.188.8.*
bit bucket? :)
Clearly isn't Fast, but suspicious behavior none-the-less.
