CMDB owners need CIs to contain all domain system names (DNS) associated with their system. Starting in Agent Client Collector for Visibility - Content (ACC-VC) version 2.3.0, ACC-VC can discover DNS name lists for Windows and Linux CIs.

When discovering DNS names associated with systems, the following occurs.

• network_adapters.rb is used to populate the DNS name for all the IP addresses using OSquery. (There is no limit.)
• Nslookupcommand is used to get the DNS name for all IP addresses.
  Nota:

  Nslookup must be configured on the target.

This creates a relationship of Owns::Owned by between the CI and the DNS names.

This information is then populated into the [cmdb_ci_dns_name] table.
