I have no clue which topic to post this in so I'll just post it here. Mods please move it if needed. I'm about to open a gaming server and I wish to allow players accessing only from European countries, USA, Brazil and Balkan countries. Basically, africa, india, asia and so on, all blocked. I've been syn/ddos attacked few months ago pretty hard and 80% of attack traffic originated from those I mentioned. Where can I get IP ranges for that?
