PowerDNS does not have limits, but if you have a lot of zones/records, you may need to increase the size and/or TTL of the caches in PowerDNS. These are the defaults: # cache-ttl=20 # max-cache-entries=1000000 # negquery-cache-ttl=60 # query-cache-ttl=20 # recursive-cache-ttl=10 Additionally, MySQL may limit you in some ways. For example, the default schema uses an INT for the domain ID, and mysql may limit this to something along the lines of 2 billion.
