Thank you for answering my PM.
Since this same issue was escalated, I was able to get the official statement please check below for it;
PXE works with Network Interface Card (NIC) of the system by making it function like a boot device. The PXE-enabled NIC of the client sends out a broadcast request to DHCP server, which returns with the IP address of the client along with the address of the TFTP server, and the location of boot files on the TFTP server. The following steps describe how it works:
- NUC is booted.
- The NIC of the machine triggers a DHCP request.
- DHCP server intercepts the request and responds with standard information (IP, subnet mask, gateway, DNS etc.). In addition, it provides information about the location of a TFTP server and boot image.
- When the client receives this information, it contacts the TFTP server for obtaining the boot image.
- TFTP server sends the boot image, and the client executes it.
Note: if you are reporting only IPv6 works, this maybe an issue with the PXE server or with the image.
