Simon,

Excited about this new feature as I now have a hardcoded prefix (which
fortunately my ISP doesn't change very often).

However, either I'm doing something wrong or there is something not working:

I changed
dhcp-range=2001:XXX:YYYY:ZZ::, ra-stateless, ra-names
enable-ra

to

dhcp-range=::,constructor:eth0, ra-stateless, ra-names
enable-ra

And in the log I see this:

Apr 17 17:11:24 dnsmasq[8972]: compile time options: IPv6 GNU-getopt
no-DBus i18n IDN DHCP DHCPv6 no-Lua TFTP no-conntrack ipset auth

Apr 17 17:11:24 dnsmasq-dhcp[8972]: DHCPv6 stateless on ::, template for
eth0
Apr 17 17:11:24 dnsmasq-dhcp[8972]: DHCPv4-derived IPv6 names on ::,
template for eth0
Apr 17 17:11:24 dnsmasq-dhcp[8972]: router advertisement on ::, template
for eth0
Apr 17 17:11:24 dnsmasq-dhcp[8972]: IPv6 router advertisement enabled

However, NO  RA's are being sent on eth0  :-(


For reference, changing back the line I get
