> For example, I want to be sure my local devices uses my local NTP server. With IPv4 it's trivial, I just add an option to the DHCP server. With IPv6 I can't do that with RA, I have to use DHCPv6. But Android doesn't support DHCPv6, so I have to run both RA and DHCPv6, and hope it just works out.
Out of curiosity, why does this require DHCPv6? Cant you just point your local devices to ntp.homedomain (or whatever the DNS name of the local NTP server is)?
I think if you're using the Meinberg NTP client on Windows, or chrony on Linux, that's feasible. Older systems may prefer to snag it from DHCP: which probably would only do IPv4 anyway.
