let's take an example. my DNS server called SrvA, the outer DNS server

normally, the client sent the query to SrvA, and SrvA forwards it to
SrvB. and SrvA return a result which came from SrvB to the client.
unfortunately the SrvB sometimes will return a A record that is a
advertisement site ip to SrvA. so i dont want to respond to client if
the returned IP address is the Advertisement site address.
filter the domain name may not be suitable.
You're better off setting up an HTTP proxy that will filter out the
bad requests. If you can't filter it by domain name, then DNS-based
filtering is not the answer.
