Name Server Configurator 介绍
NSC 是一组方便管理 DNS 服务器的工具集。
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.
