Compare A and AAAA answers during a website outage
An application can choose IPv6 while another client uses IPv4. Check both address families when the same hostname behaves differently between devices.

Use the stated shell and platform. Replace sample domains, addresses, services and paths with values from the system you are authorized to support.
Resolve-DnsName example.com -Type A
Resolve-DnsName example.com -Type AAAAHow to read the result
In Windows PowerShell, these queries separate IPv4 A records from IPv6 AAAA records. Different answer sets can be intentional, especially behind a content delivery network.
What to do next
Compare the actual connection address with the returned records. Test the intended service over each available family and investigate the failing network path instead of removing IPv6 globally.
Before you make a change
Use an approved DNS resolver for internal names. A hostname can legitimately lack one record type, so an empty AAAA answer alone is not a fault.
