DHCPv6 has a different option space that DHCP for IPv4. You probably want
something like:

subnet6 fec0:3::/64 {
	range6 fec0:3:0::100/128;
	option dhcp6.domain-search "example.org";
	option dhcp6.name-servers f3c0:3::101;
	allow unknown-clients;
}

Note that you there is no way to set an IPv4 DNS server using DHCPv6. I guess
the idea is that you should use existing IPv4 mechanisms to do that.

About the range6: you probably wanted to specify /128 rather than /64. We should
probably make it an error if you specify an invalid network (like 1:2:3:4::/8 or
something). I'll try to get this fixed for 4.0.0a2 also.
