root@binki # setup.network

01. Enter hostname
           
02. Select "DHCP" for DHCP network
    (no need for domain/ip/host config) or
    Select "static ip" for domain/ip/host config
           
03. If you chose "static ip" configuration
    Enter your fully qualified domain name
    (leave blank if you don't have/need one)
           
04. Enter your IP
           
05. Enter your Primary and Secondary DNS
    (both can be either IP or host)
           
           

setup.network modifies 2 files

root@binki # cat /etc/hosts
127.0.0.1 localhost
192.168.1.1 binki binki.example.org

root@binki # cat /etc/resolv.conf
search example.org
nameserver 192.168.1.240
nameserver dns2.example.org

You can adjust these files later with any text editor 
if you are not satisfied with setup.
Warning:
/etc/resolv.conf will be overwritten by any dhcp clients
