I’m using PDNS Authoritative Server 4.1.3, today I see my server not response and error or timeout on resolves .

When check the server see to many DNS requests from some IPs from Brazil like DDOS attack. To fix errors and timeouts, I block the attacker subnet in my firewall .

Now could you please let me know how protect my server from DOS and DDOS attacks ?
