0512667d3ebce1dd2bac2bd1de6367420402cfb3Matt Sweeney>A nameserver (NS) is a program that stores information about

0512667d3ebce1dd2bac2bd1de6367420402cfb3Matt Sweeneyact as client processes. The basic function of an NS is to provide
0512667d3ebce1dd2bac2bd1de6367420402cfb3Matt Sweeneyinformation about network objects by answering queries.</P
0512667d3ebce1dd2bac2bd1de6367420402cfb3Matt Sweeney>With the nameserver, the network can be broken into a hierarchy
0512667d3ebce1dd2bac2bd1de6367420402cfb3Matt Sweeneyof domains. The name space is organized as a tree according to organizational
0512667d3ebce1dd2bac2bd1de6367420402cfb3Matt Sweeneyor administrative boundaries. Each node of the tree, called a domain,
0512667d3ebce1dd2bac2bd1de6367420402cfb3Matt Sweeneyis given a label. The name of the domain is the concatenation of
0512667d3ebce1dd2bac2bd1de6367420402cfb3Matt Sweeneyall the labels of the domains from the root to the current domain.
b92e4372c5a34f48e457b60dfa9b136cf19c8498Matt SweeneyThis is represented in written form as a string of labels listed
0512667d3ebce1dd2bac2bd1de6367420402cfb3Matt Sweeneyfrom right to left and separated by dots. A label need only be unique
0512667d3ebce1dd2bac2bd1de6367420402cfb3Matt Sweeneywithin its domain. The whole name space is partitioned into areas
