Yeah, browsing a few if my own old questions always makes me think, "seriously? Was I that bad at Google-fu?" Though generally it boiled down to having a problem, and not knowing enough to even ask Google the right questions.
You basically had a problem related to a DNS server, so you thought that Server Fault was the place to ask for help. In reality it's more related to workstations, i.e. try asking on Super User or Unix & Linux Stack Exchange.
> Specify IP address of upstream servers directly. Setting this flag does not suppress reading of /etc/resolv.conf, use --no-resolv to do that. If one or more optional domains are given, that server is used only for those domains and they are queried only using the specified server. This is intended for private nameservers: if you have a nameserver on your network which deals with names of the form xxx.internal.thekelleys.org.uk at 192.168.1.1 then giving the flag --server=/internal.thekelleys.org.uk/192.168.1.1 will send all queries for internal machines to that nameserver, everything else will go to the servers in /etc/resolv.conf.
