Hi,
What kind of tool do you use? Webmin? Plesk? vi?
Five years ago, after evaluating Open Source and commercial solutions against similar requirements (plus simple/automated DNSSEC management), I ended up recommending (virtual) appliances from http://Infoblox.com . Essentially, they integrate BIND on top of Linux, with Web UI and a open comprehensive Perl API.
However, I migrated my own OpenBSD-based DNS servers from BIND to nsd and unbound. OpenBSD had dropped BIND from its base due to its frequent security issues, and probably also due to the difficulties its devs & maintainers at ISC went through...
