The specifications for this name server are +defined in RFC1034, RFC1035 and RFC974. These documents can be found in +\fI/usr/src/etc/named/doc\fP in 4.3BSD or \fIftp\fPed from +\fBftp.rs.internic.net\fP. +It is also recommended that you read the related manual pages, +\fInamed\fP\|(8), +\fIresolver\fP\|(3), +and \fIresolver\fP\|(5). +.pp +The advantage of using a name server over the host table lookup for host +name resolution is to avoid the need for a single centralized clearinghouse +for all names. The authority for this information can be delegated to the +different organizations on the network responsible for it. +.pp +The host table lookup routines require that the master file for the entire +network be maintained at a central location by a few people. This works +fine for small networks where there are only a few machines and the +different organizations responsible for them cooperate. But this does not +work well for large networks where machines cross organizational boundaries. +.pp +With the name server, the network can be broken into a hierarchy of domains. +The name space is organized as a tree according to organizational or +administrative boundaries. +Each node, called a \fIdomain\fP, is given a label, and the name of the +domain is the concatenation of all the labels of the domains from +the root to the current domain, listed from right to left separated by dots. +A label need only be unique within its domain. +The whole space is partitioned into several areas called \fIzones\fP, +each starting at a domain and extending down to the leaf domains or to +domains where other zones start. +Zones usually represent administrative boundaries. +An example of a host address for a host at the University of California, +Berkeley would look as follows: +.(b +\fImonet\fP\|\fB.\fP\|\fIBerkeley\fP\|\fB.\fP\|\fIEDU\fP +.)b +The top level domain for educational organizations is EDU; +Berkeley is a subdomain of EDU and monet is the name of the host. |
