Something evil is lurking on
212.95.54.22, a server belonging to black hat host
inferno.name (
mentioned here before).
I've never seen a legitimate site hosted by inferno.name, and I recommend that you block their IP ranges.. I ideidentified the following list last August, I haven't had the change to go back and check it again.
46.22.211.0/25
80.79.124.128/26
92.48.122.32/28
95.168.165.0/24
95.168.173.0/24
95.168.177.0/24
95.168.178.0/24
95.168.191.0/24
188.72.204.0/24
188.72.213.0/24
188.143.232.0/23
212.95.54.0/24
212.95.58.0/24
212.95.63.0/24
These are the some of malicious sites hosted on that server, it appears to be some sort of injection attack although it is still being analysed.

Update 15/11/12:
94.100.17.128/26 (94.100.17.128 - 94.100.17.191) is another inferno.name range that you should probably block.
