Hello together, since recently we use two powerDNS Authoritative Servers (v.4.1.8) for managing our own domains. Is it possible, to rate-limit dns lookups for non-existing Domains? Background: from time to time (several times a day), we get hundreds (or thousands) of requests to random, non-existing, subdomains for one domain, we are authoritative for. The root domain is the same in all requests. I don't understand the aim of this attacks, but want to limit it in some possible ways.
Thanks and best regards, Markus
