Radius server address can be given only as IPv4. is intentional?

I would like to use the pppoe ipv6 address to the assignment by the RADIUS server. ipv6-over-Ethernet communications in general will not be used.

To me it's not needed, but everyone would like to assign ipv6 address.

I would like to test ROS5 PC/rb411 . Email for support send

Hi
So we are waiting for ipv6 over pppoe :/
and RADIUS support for this !
