Dual stack is a means for a network interface card to support and process IPv4 and IPv6 traffic simultaneously. To be able to do this, the NIC needs to have both protocols enabled and configured to have an IP address from each version, whether that is an address that's assigned automatically or manually. This has been part of the Windows OS since Windows Vista. It could be enabled in Windows XP, but it needed some changes to be made to fully support it.
You can check whether your ISP supports dual stack by using this website: https://whatismyipaddress.com/ds-check.
