Hello, I have written a small IPv4/IPv6 config file generator (since I couldn't find one suitable for my needs). This tool can be used to generate DNS and DHCP configuration files from one central configuration file. It supports IPv4 and IPv6 addresses and reverse zone. It supports multiple subnets (including multiple dhcp servers). I hope it's useful for you too. http://www.net.in.tum.de/~gregor/projects/ Regards Gregor Maier gmm-RIPE
