        Requirements for Management of Name Servers for the DNS

Abstract

   Management of name servers for the Domain Name System (DNS) has
   traditionally been done using vendor-specific monitoring,
   configuration, and control methods.  Although some service monitoring
   platforms can test the functionality of the DNS itself, there is not
   an interoperable way to manage (monitor, control, and configure) the
   internal aspects of a name server itself.

   This document discusses the requirements of a management system for
   name servers and can be used as a shopping list of needed features
   for such a system.
