The labs DNS server only returns a single DNS resolver:
A DHCP lease:
```
lease {
interface "eth0";
fixed-address 10.68.16.187;
filename "jessie-installer/pxelinux.0";
server-name "carbon.wikimedia.org";
option subnet-mask 255.255.248.0;
option dhcp-lease-time 86400;
option routers 10.68.16.1;
option dhcp-message-type 5;
option dhcp-server-identifier 10.68.16.1;
option unknown-209 "pxelinux.cfg/ttyS1-115200";
option domain-name-servers 208.80.155.118;
option dhcp-renewal-time 43200;
option dhcp-rebinding-time 75600;
option broadcast-address 10.68.23.255;
option host-name "ci-jessie-wikimedia-147750";
option domain-name "eqiad.wmflabs";
renew 4 2016/06/16 07:55:36;
rebind 4 2016/06/16 17:04:15;
expire 4 2016/06/16 20:04:15;
}
```
What ever DHCP server is answering would probably need the second labs resolver to be filled:
```
lang=diff
- option domain-name-servers 208.80.155.118;
+ option domain-name-servers 208.80.155.118, 208.80.154.20;
```
In puppet we have modules/openstack/templates/liberty/nova/dnsmasq-nova.conf.erb :
```
lang=erb
#Clients should use the designate-backed dns server rather than dnsmasq
dhcp-option=option:dns-server,<%= @recursor_ip %>
```
Potentially if `@recursor_ip` is found out to be list/array, we could sort and join with `,` all the entries.
