As indicated in:
https://www.linuxquestions.org/questions/linux-newbie-8/there-are-many-query-this-website-on-my-dns-server-4175676097/

The solution is to Include the following lines in '/usr/local/csf/bin/csfpre.sh' file:

Code: [Select]
iptables -A INPUT -p udp --dport 53 -m string --algo kmp --string "pizzaseo" -j DROP
iptables -A INPUT -p udp --dport 53 -m string --algo kmp --from 0x38 --hex-string "|0000ff00010000292328000000000000|" -j DROP

And restart csf/lfd:

Code: [Select]
csf -x; csf -e

Thank you Netino,

You're save my life, add again "census" to block and it working!

Does anyone know how to block them?
I'm going to clear the server cache, hope that helps ...
