[Pdns-users] dns flood problem

[Steffan Noord]

Hello Nick,

Do you want to share your config with me.
Wat are dns queries that we want to block ?

Im starting the logs of pdns on a higher level
I see some of these errors

Received a malformed qdomain from 194.xx.xx.xx, 'error(2):\032Connection\032to\032service\032failed.xxx.com': sending servfail
