"Suppose you are running some public services, and you want to
control your own authoritative DNS server. The alternative is to
use a third-party service to manage your DNS, such as the
hostmaster at your ISP, or your domain name registrar. But you
would rather retain control yourself, for faster (and possibly
better) service. While I think it is good for network and system
administrators to have as much control as possible, the Internet is
infested with mis-configured DNS servers, so please be careful and
make sure you get it right."
