Hi Oliver, I’ve a similar/same problem when rebooting some QNAP NAS boxen, first boot/introduction to dnsmasq and they get both IPv4 & v6 addresses set to fixed values based on MAC address. On reboot whilst IPv4 is fine, IPv6 is not reallocated to the original address but rather a new one. By curious co-incidence I just started looking into this problem today though it has been bugging me for months :-) Have tried various combinations of MAC address & DUID. Without meaning to thread hijack! If it’s not effectively the same issue will gladly start a new thread.
