| 
| resolv.conf:
| nameserver 192.168.1.1
| search gotdns.org
| 
| network/interfaces:
| allow-hotplug eth1 
| iface eth1 inet static 
|   address 192.168.1.251 
|   netmask 255.255.255.0 
|   network 192.168.1.0 
|   broadcast 192.168.1.255 
|   gateway 192.168.1.1 
|   # dns-* options are implemented by the resolvconf package, if installed 
|   dns-nameservers 192.168.1.1 
|   dns-search gotdns.org

| 
| hosts:
| 127.0.0.1 localhost
| 192.168.1.251 yam.gotdns.org yam
| 
| Does any of that help?

bash-3.1# cat /etc/resolv.conf
search azurservers.com
nameserver 212.27.53.252
nameserver 212.27.54.252

bash-3.1# cat /etc/hosts
127.0.0.1               localhost
192.168.0.1             azurservers.com darkstar
192.168.0.2             azurservers.com darkstar1
192.168.0.254           gateway
82.242.110.54           azurservers.com

This works just fine for me
