If you are seeing queries for this domain, than you are likely participating in DNS Amplification attacks and your DNS server is probably reachable from the internet and has recursion enabled.

If you are seeing responses for this domain.. unlucky. You are currently beeing DDOS-ed! Good luck.


There are two iptable rules available. If your distribution supports Iptables 'u32' module pick this one, otherwise use the 'string' rule.

This rule should match any single char subdomain for

iptables --insert INPUT -p udp --dport 53 -m u32 --u32 "0x28&0xFF00FFDF=0x01000453 && 0x2c&0xDFDFDFFF=0x4c4e4d04 && 0x30&0xDFDFDFDF=0x494e464f && 0x34&0xFF000000=0x00000000" -j DROP -m comment --comment "DROP DNS Q"

More U32 rules can be found here:

iptables --insert INPUT -p udp --dport 53 -m string --from 42 --to 53 --algo bm --hex-string '|04736c6e6d04696e666f00|' -j DROP -m comment --comment "DROP DNS Q"
More Iptables rules for the STRING module can be found here:
