MultiBIND Admin is a web-based BIND DNS zone file administration tool written in PHP. It manages forward and reverse DNS as well as most common record types (though it is currently IPv4 only). Its main feature is understanding of NATed split-horizon environments, where each record is stored with separate internal and external view addresses, and these are automatically mapped to the appropriate views.

This collection of scripts manages DNS in a MySQL database, and then the bin/multibind-update.php script is run on the master BIND server to pull down data for and re-write all changed zone files.

I used this project for internal DNS for my home network and sites for about three years, and it served me quite well.
