I oppose adoption. Any implementation of this draft will actively hurt the DNS and the Internet, and thus publication as an RFC will actively hurt the DNS and the Internet.

The draft doubles the number of packets involved in a legitimate exchange; it more than doubles the number of packets involved in a spoofed exchange. About half of these packets are ICMP packets. Without the draft, ICMP packets are useful debugging aids, and in big numbers, indications of attacks or operational problems. With the draft, ICMP becomes another useless source of background noise.

Meanwhile, we have no indication that the draft solves any existing real world problem in a useful way.

Please do not adopt.

Kind regards,
