[Help]DNS DNS cache poisoning attack

I'm running a game server on my own network and it is seems to be getting some different attacks daily, as much as I know it is the same person who is doing the DNS attack, in my country the IP changes everyday but I'm lucky his IP goes betwen 194.90.0-255.0-255, I have tryed to block his IP range but probably it isn't really working, any suggestions?

Here you can find the log:

Hello Martoon
If you do a IP lookup, is seems that it is coming from someone called netvision.net.il in Israel. -http://www.013netvision.net.il/- Regarding blocking a certain ip address maybe this link can help you: http://kb.eset.com/esetkb/index?pag...earch&viewlocale=en_US&searchid=1309444272179
I presume you are using Eset RC 5, it that case go to " Enter advanced setup" then click on "Web and email" and got to "Web access protection" expand and go to Url address management.
Take Care

The ISP called netvision not the attacker, netvision is a internet provider in my country.
