It is misunderstood of DNS service. While all computers
come to full redundancy throught some cluster servce,
DNS has redundancy on its application level.

What is mean master/slave in DNS ? You have not duplicate
non master, neither slave ! It is already redundant !
Slave configuration copies its configuration from master
automatic (at some period of time) without your intervention.
While master fail, slave still available, and vice versa.

Two different DNS servers configured as master/slave
are definetely enought for any purpose. It is good 
practice that both of them resides on different networks
and ISPs, however.
