How to Set Ubuntu Server IP

Configuring Ubuntu Server IP have never been any easier. Just edit the /etc/network/interfaces file using any text editor on the server. By default, you should have nano and vi in your Ubuntu Server.



The simplest and straight forward text editor is nano. So, use this command:


$ sudo nano /etc/network/interfaces



you should see the default file content like this:


# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interfaceauto loiface lo inet loopback
# The primary network interface
   auto eth0
    iface eth0 inet dhcp



This is the default network settings on your Ubuntu Server where it use DHCP. So, to set it as static IP. Let say, we wanna setting like this:


=> Host IP address: 10.1.1.100


=> Netmask: 255.255.255.0

=> Network ID: 10.1.1.0

=> Broadcast IP: 10.1.1.255

=> Gateway/Router IP: 10.1.1.254

=> DNS Server: 10.1.1.254




You should change the file like this:



# This file describes the network interfaces available on your system
#  and how to activate them. For more information, see interfaces(5)
# The loopback network interfaceauto loiface lo inet loopback
# The primary network interfaceauto eth0
# iface eth0 inet dhcp
  iface eth0 inet static
  address 10.1.1.100
  netmask 255.255.255.0
  network 10.1.1.0
  broadcast 10.1.1.255
  gateway 10.1.1.254




To set the DNS server, edit the /etc/resolv.conf file using this command:





$ sudo nano /etc/resolv.conf



add the line for nameserver like this:

search myisp.com
nameserver      10.1.1.254
nameserver     208.67.222.222
nameserver     208.67.220.220
