All name server software (including PowerDNS) could be used for it as long
as an IP can request DNS packets from it. Some attackers are smart and start
by gathering a list with domains with a big zone in it on a name server and
The only option to prevent it is by blocking ALL traffic on port 53 UDP +
TCP (valid for all name servers running on the default DNS port 53).
