DNS BIND, which stands for Berkeley Internet Name BIND/iX
Domain, is an implementation of the Domain Name System (DNS) and
is the most commonly used of the Domain Name System (DNS). Now,
the complete implementation of DNS BIND/iX runs on MPE/iX shell
operation system on MPE/iX release 6.0. Initially, DNS BIND/iX was
written for UNIX. Now, the latest version of DNS BIND/iX 8.1.1 runs on
MPE/iX systems.
Overview of DNS BIND/iX
DNS BIND/iX is a domain name system which consists of a
client-server mechanism. The name-servers comprise the server half of
the DNS’s client-server mechanism. The name-server is the NM
program NAMED which maintains information about some part of the
DNS called a zone and has capabilities to retrieve information
regarding other zones. The clients are resolver routines provided as
NMRL libraries. The resolvers are clients that query the name servers,
interpret the responses and send the answers to the requester.
DNS BIND/iX makes your domain names visible to the internet as well
as handling client requests to resolve domain names within your
domain and external domains. Prior to DNS BIND/iX, the HP 3000
users had to rely on other machines or other operating system to host
their organization DNS information. Now, you can host it on HP 3000
systems.
The latest version of DNS BIND/iX 8.1.1 is available for MPE/iX release
6.0 with the following features:
• DSN Dynamic Updates
• DNS Change Notification
• Completely new configuration syntax
• More efficient zone transfers
The BIND/iX contains the following major utilities and administration
tools:
nslookup The nslookup utility can be used by users to query the
name servers interactively
DIG Domain Information Groper.
named-xfer The named-xfer utility is used to transfer the zone
information and called by name-server internally.
