Using IPv4 and NAT, the failure of one NAPT box fails all the call calls going through that box because they would get different IPv4 addresses on a different NAPT box. With IPv6, the calls automatically reroute around the failed box through another box and continue because the addressing does not change.

Dual-stack: In dual-stack configuration, the device is configured for both IPv4 and IPv6 network stacks. The dual-stack configuration can be implemented on a single interface or with multiple interfaces. In this configuration, the device decides how to send the traffic based on the destination address of the other device. IPv4 and IPv6 Interoperability. During the gradual transition phase from IPv4 to IPv6, existing IPv4 applications must continue to work with newer IPv6–enabled applications. Initially, vendors provide host and router platforms that are running a dual-stack. A dual-stack is both an IPv4 protocol stack and an IPv6 protocol stack. Using IPv4 and NAT, the failure of one NAPT box fails all the call calls going through that box because they would get different IPv4 addresses on a different NAPT box. With IPv6, the calls automatically reroute around the failed box through another box and continue because the addressing does not change. Stack Exchange network consists of 177 Q&A communities including Stack Overflow, One of the first ones I did was on modeling an IPv4 address in C++.

[Image: Dual Stack Router] In the above diagram, a server having IPv4 as well as IPv6 address configured for it can now speak with all the hosts on both the IPv4 as well as the IPv6 networks with the help of a Dual Stack Router. The Dual Stack Router, can communicate with both the networks.

IPv4 vs IPv6: What’s the Difference? - Guru99 Jul 13, 2020 Network Stack IPv4 and IPv6 Commands - Cisco Jun 22, 2020 Start pxe over ipv4 - boot issues - Microsoft Tech Re: Start pxe over ipv4 - boot issues PXE is usually set to be the fallback option when there's no other boot device (hard disks, CD drives, USB drive, etc.). If you see your system is attempting PXE boot, there is a very good chance your booting devices are not available for boot.
