Dual stack helps resolve all scenarios where both IPv4 and IPv6 are involved, because it enables devices to support and communicate over both IPv4 and IPv6 networks. Drop comments for each scenario on how it works

What Is Dual Stack?
Dual Stack means a device (like a router, server, or computer) is configured to run both IPv4 and IPv6 simultaneously. It can communicate using either protocol, depending on what the other device supports.
How It Works:
<ul data-start=”458″ data-end=”779″>
Devices and applications prefer IPv6 if it’s available.
If IPv6 is not available (for example, the destination only has IPv4), the system will fall back to IPv4.
Network interfaces have two IP addresses: one IPv4 and one IPv6.
DNS (Domain Name System) can return both A (IPv4) and AAAA (IPv6) records.
