Does DNS have to be on a domain controller?

In a small environment, at least one domain controller (DC) should be a DNS server. It is possible to install DNS on servers which are not DCs, including non-Windows servers, but installing DNS on DCs allows the use of AD-integrated lookup zones (see below), which improve security and simplify zone replication.
