This is the salient part of the configuration file (the rest is basically defaults):

That prefix is good and I presume if I let it set the other interfaces it will be ok.
But if I do not say "ipv6only", leaving it that commented out so I can get both, I get on dhcpcd -T:

Hi Roy, Thank you very much for the configuration example with dhcpcd! Also I didn't know delayed auth had been obsoleted, thanks for letting me to notice. I'll try dhcpcd instead of dhcp6c. Best Regards,
