Use clean version of 'hosts' files (C:\Windows\system32\drivers\etc). Or just make clean one.
It's caused of 'forwarding' data.
If you have line in 'hosts' file like:
192.168.1.1 9dragons.gamescampus.com
it makes the system think: 'oh, when I see that address, I should move to the 192... ip thing!'.
