Explain why two name servers is the minimum number you would ever want to run in an organizations networked IP environment. Consider the following factors, which can influence the total number of name servers present on a typical organizations internetwork:

If a name server is available directly on each network or subnet in a local internetwork, routers need not become potential points of failure. Consider also that multihomed hosts make ideal locations for DNS because they can directly service all the subnets to which theyre connected.

In an environment in which diskless nodes or network computers depend on a server for network and file access, installing a name server on that particular server at a minimum makes DNS directly available to all such machines.

Where large time-sharing machinessuch as mainframes, terminal servers, or clustered computersoperate, a nearby DNS server can offload name services from the big machine, yet still provide reasonable response time and service.

Running an additional name server at an off-site locationlogically, at the site of the ISP from which your organization obtains an Internet connectionkeeps DNS data available even if your Internet link goes down or local name servers are unavailable. A remote secondary name server provides the ultimate form of backup and helps to ensure DNS reliability.

Given the foregoing information and the fact that the organization operates three subnets at each of its Indiana locations along with a large clustered terminal server at each location, explain how XYZ might want to operate as many as nine name servers for its network environment.

Please help me, I am very confused when it comes to networking.
