No normal person will ever generate reverse zone manually. But forward zones are also not that great as bind syntax is pretty obscure and unless you use sophisticated features is an overkill.
CyberDNS is a Web application to manage DNS zones and BIND configurations easily. It lets you add entries and then watch as they are generated into zone and configuration files. It supports IPv6 and most DNS types. The Web interface runs on the master DNS server, and cron is used to synchronize the Sqlitedb and zone files to slave DNS servers. It is easy to make snapshots to revert in the event of failure.

NSC is a set of utilities for easy administration of DNS servers. You write very simple configuration files and NSC automatically generates zone files, reverse zone files, and configuration for the BIND. Among other things, it also supports classless reverse delegations and IPv6 addressing. NSC is written in POSIX shell and GNU M4, and it should run on all systems where these two languages are available. Generation of DNS daemon config files is currently limited to BIND 8 or 9, but it's very easy to add your own config file generators for other daemons.
HostdbA system for generating internal DNS zones, external DNS zones, and DHCP configuration data from the same hostlist.txt file. Keep your configurations consistant by generating them all from the same source. The files that are generated are beautifully formated and easy to "diff" before they are put into production. It even generates the Makefile required to make the system all work together. A "file push" mechanism (mkdestinations), plus many DNS-related utilities are included (sortbyip, genrange, comparezones, checkrootcache).Released under the GPL on January 8, 2005. Current release: 1.002
First unveiled at the Usenix LISA 2005 Conference, San Diego, December 4-9, 2005 under the title, "HostDB: The Best Damn host2DNS/DHCP Script Ever Written".
- 2008-02-06: 1.002 released. Improved genrange, canonzone, and adds HIDEMASTER and DOMAINMX keywords to zoneconf.txt. See README.txt and examples/goodstart/zoneconf.txt for more info.
- 2006-07-05: RPM available. Antoine Brenner as created a source rpm for centos4 (should be fine with most rpm-based distributions). link. Thanks Antoine!

DNStool 2.2 administration guide
The Domain Name Service (DNS) auto-configuration system (DNStool) is designed to take the pain out of managing DNS. It does this by automatically generating DNS files from a small number of configuration files. DNS files are in a complex and repetitious format; mistakes or omissions often creep in when manually maintained. In general, it reduces the task of maintaining DNS to 3 steps:
- for each domain, maintain a database describing its hosts
- maintain a description of the common features across domains
- run the configuration programs to generate DNS configuration files and install them.
This document is aimed at DNS administrators and is a description of these three steps in modifying the configuration. The DNS autoconfiguration system does not remove the need to understand the basics of DNS (and the DNS auto-configurer) in order to make major changes to the DNS configuration

Generation of zones from /etc/hosts file
h2n, a tool for converting a static hosts file into DNS zone files. Originally written by Cricket Liu for the O'Reilly DNS and BIND book. Currently maintained by Hal Pomeranz.
h2n - a host table to name server file converter. You can use h2n to create your data the first time and then maintain your DNS data manually. Or, you can use h2n over and over again. As you have seen, the format of the host table is much simpler to understand and to modify correctly. So, you could maintain /etc/hosts and rerun h2n to update your DNS data after each modification.
If you plan to use h2n, you might as well start with it, since it uses /etc/hosts - not your hand-crafted DNS data - to generate the new DNS files. We could have saved ourselves lots of work by generating the sample data in this chapter with the following:
h2n -v 8 -d movie.edu -s terminator -s robocop -n 192.249.249 -n 192.253.253 -u al.robocop.movie.edu
The -d and -n options specify the domain name and network numbers. You'll notice that the db filenames are derived from these options. The -s options list the name servers for the NS records. The -u (user) is the email address in the SOA record.

Updatehosts ftp://ftp.tic.com/pub/updatehosts/updatehosts-1.0.0.tar.gz -- is a system for automatically managing and generating DNS zone files using flat relational tables. Some of the features of updatehosts includes:
dnsupdate -- does not make any sense other then exercise in C
In search for a program that would help me create and maintain the DNS databases, my efforts were in vain. The nearest ones I could find were written in perl. The last thing I wanted to do from my program was to do a "system" call. I started playing with BIND 8.2.2 P7 and converted the nsupdate program to a function. That actually made me write the rest of the program.
My benchmark program was the famous h2n perl script. dnsupdate seems to be much faster than h2n. I have given a timing comparison table between dnsupdate and h2n in Appendix B.
With my highly limited knowledge about DNS or its configuration files (DNS tables or DNS databases) I am requesting users of this program to pinpoint any errors or suggestions to make dnsupdate a better one.
