The router menus make no mention of IPv6 configuration, DHCP refers only to IPv4 and is working. One of the Pis has Kea installed but with no interfaces configured for IPv4 or IPv6. All three of my Linux computers have IPv6 addresses, the sid workstation having two. I've never used it so I've no idea where they have come from.
