One of the major benefits to the design of the Internet is the redundancy that is built-in. To provide
a measure of fault tolerance for DNS on the Internet, the designers of the Domain Name System

disable DNS, they would have to gain administrative access on all the root servers. How many
DNS servers would have to be compromised to have complete control of the Internet DNS?
