I would say something along the lines of adding this to your dnsmasq
config:

enable-ra
dhcp-range=2a01:348:6:876d::,slaac

(then fine-tune the RA parameters, also add an ra-param line, see the
man page)

If you also give (and resolve) names for your local machines, then you
might want to put "ra-names" instead of "slaac".

Amicalement,
