What is DNS Management ?

Question

DNS Management ?

Answer 1

DNS management software is software that runs Domain Name System server clusters. Its main purpose is to reduce human error when editing the somewhat complex and repetitive text DNS server configuration files. Worse, these files tend to be deployed on several if not dozens of different remote physical servers.

Initially large DNS service providers relied heavily on system administrators and their own personal collection of Perl or Shell scripts that provided some automation for managing large sets of DNS zones across a cluster of servers. This proved to be very expensive and also prone to human error, relying heavily on single DNS administrator "gurus."

The current state-of-affairs of large DNS service providers is one where a complex mix of different types of DNS servers co-exist, along with the added complexity that different zone resource records must be provided to the DNS client based on their network IP range (usually similar to a geographical location). The only practical way to manage such critical internet infrastructure has been to rely on databases and complex DNS management software to insure homogeneity and avoid single points of deployment errors.

Some DNS software includes these high level management tools. The most widely used DNS software, the Internet Systems Consortium(ISC) BIND DNS server software does not have high level (server cluster) management software.
