Final answer:
In a dual-stack configuration, IPv4 and IPv6 networks can coexist and communicate with each other.
Step-by-step explanation:
In a dual-stack configuration, IPv4 and IPv6 networks are able to coexist and communicate with each other. This means that devices running on an IPv4 network can communicate with devices running on an IPv6 network, and vice versa.
The dual-stack approach involves configuring devices to support both IPv4 and IPv6 protocols simultaneously. This allows for a smooth transition from IPv4 to IPv6 without disrupting communication between networks.
For example, if a website is dual-stacked, it will have both an IPv4 and an IPv6 address. When a device with an IPv4 address tries to access the website, it will communicate using IPv4 protocols. When a device with an IPv6 address tries to access the same website, it will communicate using IPv6 protocols. This ensures compatibility between IPv4 and IPv6 networks.
