You can use iptables to rate-limit the IP.

All. 

 

There is huge traffic coming out from my DNS server since yesterday and
flooding the IP 212.107.121.110, though I have increased the limitation of
tcp-clients in named.conf but still the issue.  any help would be highly
appreciate.

 

 

My bind version is 

 

[root at ns10 ~]# named -v

BIND 9.9.2-P1

 

 

 

When checking  there are several entries as below. 

 

Jul 26 10:53:26 ns10 named[3004]: client 212.107.121.110#4636: no more TCP
clients: quota reached

quota reached
