<br>
I've recently switched to using only dnsmasq on openwrt since finding<br>
out that it could also hand out IPv6 addresses. This works, but the<br>
clients only get SLAAC addresses.<br>
<br>
Also, the manpage states:<br>
<br>
"A single dhcp-host may contain an IPv4 address or an IPv6 address, or<br>
both. IPv6 addresses must be bracketed by square brackets thus:<br>
--dhcp-host=laptop,[1234::56] Note that in IPv6 DHCP, the hardware<br>
address is not normally available, so a client must be identified by<br>
client-id (called client DUID in IPv6-land) or hostname."<br>
<br>
How do I find this client-id/DUID? Even with the "log-dhcp" directive,<br>
I don't see anything that looks like it.<br>
<br>
Here are my conffiles. openwrt auto-generates a /var/etc/dnsmasq.conf<br>
based on a file written in their own DSL (/etc/config/dhcp), which is<br>
it's split in two files.<br>
