Dear Mohamad,

My Server is public and I offer my service to lots of domains so I can't
specify the subnets.

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 ?


Best Regards,
