To clarify, Arbor Network doesn't produce firewalls, but rather 
intelligent DDoS mitigation systems, or IDMSes.

I'm unaware of any feature in Arbor products which by default does 
what's being described; operators of our IDMSes do have the ability to 
filter packets, including DNS queries, but they're typically 
operator-configurable.

Please feel free to ping me directly so that we can understand the 
details better, and go from there.

Thanks for reaching out, and to Barry for cc'ing me directly!
