Managing DNS Resource Records

A resource record, commonly referred to as an RR, is the unit of information entry in DNS zone files; RRs are the basic building blocks of host-name and IP information and are used to resolve all DNS queries. Resource records come in a fairly wide variety of types in order to provide extended name-resolution services.

Different types of RRs have different formats, as they contain different data. Many RRs share a common format. Each DNS Server contains RRs for the portion of the name space for which it is authoritative.

The DNS WMI Provider currently supports the following RR types. Click the name of the resource record to jump to its reference page.

Administration Steps

The DNS WMI Provider enables the administration of RRs from the server itself, or from remote hosts. The general steps necessary to administer RRs using the DNS WMI Provider are:

  • Connecting to the DNS WMI Provider
  • Getting a resource record instance
  • Listing or modifying a resource record property or using a method

The following tasks are linked to their associated scripting samples.
