[Dnsmasq-discuss] dnsmasq with dhcpv6 and dhcp-host option

Mon Jan 14 17:49:07 GMT 2013

Hi Simon,

Thank you for help! It's the problem!

However, after I correct this one, dnsmasq still failed to hand out IP
address, using dhcp-host entry.

The config here:
dhcp-range=fc00:1234:5678:1234::1,static
dhcp-host=00:01:00:01:18:80:df:3e:48:aa:8e:b2:d5:2a,fred,[fc00:1234:5678:1234::144],test,infinte
enable-ra

The log:

I would be appreciate if you can help!

Thank you!
