You can use iptables to rate-limit the IP.

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
