DNS Hidden Master – InetDaemon’s IT Tutorials – Hidden master” is the term given to describe a special DNS configuration that protects the master DNS server from attack. This configuration conflicts with the expected standard configuration and registration process, and will often confuse most inexperienced DNS administrators. As if this weren’t enough, it relies on both an Internet connection, a carefully configured DNS server AND a properly configured firewall. There is a lot that can go wrong with this configuration most of which has nothing to do whith the DNS server itself. Once any DNS problems start, it is nearly impossible to determine the real cause.
