DNS traffic generator

Can anyone advise on the best tool to generate DNS response traffic or DNS traffic with query payload?

I am looking to generate traffic and test my security appliance to pick up dns amplification attacks where victims receive dns response from domains to queries they never initiated. I am using Regex to capture on payload and block it that way but was looking to do some testing to auto-detect on dns amp type attacks.

For ex: dns response from domain.com(500k)—->victim:1.1.1.1/32 In this victim never requested the page domain.com but still received it

I have heard of Trex and Hping but wasn’t exactly sure to craft a packet that would generate lot of dns responses.

Any help would be helpful.
