[Dnsmasq-discuss] ipv6 dhcp range mode static does not work

[s***@zstack.io]

Hi Guys,



I deploy a dnsmasq with
¡°dhcp-range=2234:aabb:ccff:ffe::2,2234:aabb:ccff:ffe:0:ff:ffff:ffff,static,
120,24h¡±£¬ I hope that dnsmasq will reply success ONLY when the [mac, ip]
match the binding in dhcp-hostfle.

But dnsmasq will reply success when it received a dhcp confirmation with
[mac, ip] not in dhcp-hostfle.

Do you have any idea how to achive this?

Thanks in advance.

here is the the conf file:

# ps -aux | grep dns
nobody 16473 0.0 0.0 15604 980 ? S 11:33 0:00 /usr/sbin/dnsmasq

From the manpage of dnsmasq:

"The optional keyword may be static which tells dnsmasq to enable DHCP for
the network specified, but not to dynamically allocate IP addresses: only
hosts which have static addresses given via --dhcp-host or from /etc/ethers
will be served."
