This is generally not a big issue for dual-stacked residential customers as most CPEs does SLAAC on the LAN-side, but the Win10 clients will not recieve DNS from DHCP if the CPE is configured for that. For enterprise networks on the other hand this can be a big issue. Especially when running FHS and no SLAAC. Have anyone on the list experienced issues with this yet? If so, have you contacted Microsoft and what did they say? I've found reports on this issue dating back from early august so it's strange that Microsoft have not yet issued a fix for it. -- Harald
