Internet Express for Tru64 UNIX Version 6.8 Administration Guide (14233)

18 BIND Domain Name Server Administration
The Domain Name System (DNS) is a hierarchical, distributed database that stores information
for mapping Internet host names to IP addresses and vice versa. It also stores mail routing
information and other data used by Internet applications.
The Internet Express version of the Berkeley Internet Name Domain (BIND) implements a domain
name server for the Tru64 UNIX operating system.
This chapter provides information that helps you enable the latest version of BIND and manage
the BIND server. It contains the following sections:
• BIND overview (Section 18.1: BIND Overview).
• Location of BIND files and directories (Section 18.2: Important BIND Files and Directories).
• Enabling the latest version of BIND provided by Internet Express (Section 18.3: Enabling
BIND).
• Running the BIND startup script (Section 18.4: Running the BIND Startup Script).
• Documentation provided with BIND Section 18.5: BIND Documentation.
18.1 BIND Overview
The Internet Domain Name System (DNS) consists of the syntax to specify the names of entities
in the Internet in a hierarchical manner, the rules used for delegating authority over names, and
the system implementation that actually maps names to Internet addresses. The Internet Express
version of the Berkeley Internet Name Domain (BIND) implements a domain name server for
the Tru64 UNIX operating system. Using BIND, DNS data is maintained in a group of hierarchical
databases.
Clients look up information in DNS by calling a resolver library. This library sends queries to
one or more name servers and interprets the responses. BIND Version 9.2.0, provided with
Internet Express, is a complete rewrite of the Internet Software Consortium's BIND code base
that contains both a name server and a resolver library.
18.2 Important BIND Files and Directories
Table 18-1 contains information about files, commands, and reference pages that helps you
administer your BIND server. For further information about performing specific BIND
administrative tasks, see the BIND administrator's reference and other information from the
BIND Web site:
