Log on to the DNS server using the Domain Admin or Enterprise Admin account or Local Administrator account.

Press the Windows key + R and execute "dnsmgmt.msc".

On the opened DNS Manager snap-in from the left pane, expand the server name for the DNS server and then expand "Forward Lookup Zones".

From the expanded list, select each zone and examine the host record entries. The third column titled "Data" will display the IP.

Determine if any contain both IPv4 and IPv6 addresses.

If any hostnames contain both IPv4 and IPv6 addresses, confirm with the system administrator that the actual hosts are in a dual stack.

If any zones contain hosts with both IPv4 and IPv6 addresses but are determined to be not in a dual stack, this is a finding.
