==What if I run a DNS server on purpose?==
It is quite legitimate for people to run DNS servers on their Network - in these cases access to them should be restricted or limited.
If you run an Authoritative DNS server, configure it only to return records for your domain.
If you run a Caching resolver, configure it to only return records for your users (firewall to only allow your users), and consider implementing rate-limiting.
=How to prevent this?=
