At my place of employment, we are using Linux as a DNS server and it performs exceptionally well.
This section will address configuration of DNS tables for these services using the BIND 8.x package which is standard with the Red Hat distribution.
Note: Note: Red Hat versions 5.1 and earlier used the BIND 4.x package, which used a slightly different format for its configuration file.
BIND 8.x offers more functionality over that offered by BIND 4.x, and as 4.x is no longer being developed, you should probably consider upgrading your BIND package to the latest version. Simply install the BIND RPM package (see Section 10.1 for details on using the RPM utility), then convert your configuration file to the new format.
Fortunately, converting your existing BIND 4.x configuration file to be compliant with BIND 8.x is easy.
In the documentation directory provided as part of BIND (for example, /usr/doc/bind-8.1.2/ for BIND version 8.1.2), there exists a file called "named-bootconf.pl'', which is an executable
Assuming you have Perl installed on your system, you can use this program to convert your configuration file. To do so, type the following commands (as root):
./named-bootconf.pl < /etc/named.boot > /etc/named.conf
mv /etc/named.boot /etc/named.boot-obsolete
You should now have an "/etc/named.conf'' file which should work with BIND 8.x "out-of-the-box".
Your existing DNS tables will work as-is with the new version of BIND, as the format of the tables remains the same.
