Currently IPv6 addresses are assigned to tuple (IAID, DUID). When system
changes IAID/DUID then old assigned IPv6 address cannot be reused, even
when in config file was DHCPv6 assignment based on MAC address (and not on
DUID).
IAID/DUID is changed when rebooting from one operating system to anothe

Hello! There is similar issue also for IPv6 addresses for which I have

Before this patch when both RADV and DHCPv6 is running and DNS server

Thats probably truth, but if something is useful users will try to use
it. Either itself by patching dnsmasq or if possible by optional config
options...

I think it is possible to configure dnsmasq to assign only configured
ipv4 address for mac address.
For dhcpv6 I have own dnsmasq patches which assign ipv6 address bases on
mac address...

ing like this in dnsmasq.conf:
enable-tftp
tftp-root=/var/lib/tftp
dhcp-vendorclass=set:PXE,PXE
dhcp-userclass=set:iPXE,iPXE
dhcp-boot=tag:PXE,"undionly.kpxe"
dhcp-boot=tag:iPXE,"http://my.web.server/...";
Generic PXE clients receive iPXE binary and iPXE clients receive U
prefix. Routing in IPv6 is done via Router Advertisement (which dnsmasq
supports too). What is the output of route -n? Is there route for that
your fda0:4d7f:afbb:: prefix?
