.sh 1 Introduction

|
|
The Berkeley Internet Name Domain (\s-1BIND\s+1) implements an Internet name
|
||
|
|
server for \s-2BSD\s+2-derived operating systems. The \s-1BIND\s+1 consists
|
||
|
|
of a server (or ``daemon'') called \fInamed\fP and a \fIresolver\fP library.
|
||
|
|
A name server is a network service that enables clients to name resources or
|
||
|
|
objects and share this information with other objects in the network. This
|
||
|
|
in effect is a distributed data base system for objects in a computer
|
||
|
|
network. The \s-1BIND\s+1 server runs in the background, servicing queries
|
||
|
|
on a well known network port. The standard port for UDP and TCP is specified
|
||
|
|
in \fI/etc/services\fP. The \fIresolver\fP is a set of routines residing
|
||
|
|
in a system library that provides the interface that programs can use to
|
||
|
|
access the domain name services.
|
||
|
|
.pp
|
||
|
|
BIND is fully integrated into BSD (4.3 and later releases)
|
||
|
|
network programs for use in storing and retrieving host names and address.
|
||
|
|
The system administrator can configure the system to use BIND as a
|
||
|
|
replacement to the older host table lookup of information in the network
|
||
|
|
hosts file \fI/etc/hosts\fP. The default configuration for BSD uses
|
||
|
|
BIND.
