This is just a simple tool that takes your network information, and generates BIND zone entries. This tool is designed to create forward and reverse records for your DHCP range.
For example, if you wanted to name all of the dynamic-IP clients in your network "dhcp-###.office.corporate.com", where "###" is the C-block of each IP address, this tool allows you to generate the BIND records for that, both A and PTR.
