Each name server stores information about its domain in the form of several different kinds of resource records, each of which stores a different kind of information about the domain and the hosts in the domain.

Resource records are traditionally text entries stored in different files on the domain name server.
The Cisco DNM Browser lets you edit these records via a graphical interface, reducing the chance of errors in the text files. The following is A description of the different DNS Resource Record Descriptions record types and descriptions available on the DNM Browser

• Start of Authority (SOA) Required for every domain. Stores information about DNS itself for the domain.
• Name Server (NS) Stores information used to identify the name servers in the domain that store information for that domain.
• Address (A) Stores the host name and IP address of individual hosts in the domain. This is the record used to translate host names to IP addresses.
• Canonical Name (CNAME) Stores additional host names, or aliases, for hosts in the domain.
• Mail Exchange (MX) Stores information about where mail for the domain should be delivered.
