[dns-operations] High qps for type32xxx records

Sorry had to change subbed address to resend.

Anyone else seeing a huge increase for requests for $random.$tld type32xxx +dnssec (changes) hitting their auth server? Were doing about 5 , times our normal query rate intermittently over the last 3 days (not a problem, but interested what it is)

Doesn't look to be from a spoofed sources as per a normal amplification attack (and were using rrl already)

I know another providers seeing the same.

Any ideas what they are trying to do? It's all nxdomain responses plus the dnssec records.

Cheers
Ben
