Set Static IP Address for Ubuntu/Debian Server

[vc_row][vc_column][vc_column_text]If you install an Ubuntu/Debian server, by default, it is only set up with DHCP and hence it fetches an IP address automatically from the DHCP server. In order to change the DHCP IP address to a static IP address you can edit /etc/network/interfaces file of your server and set it to static IP address as follows:

Content of original file:

{code}
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp
{/code}

Now, remove dhcp and change it to static. Below that enter the details of your static IP address.

Updated interfaces file:

{code}

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static

netmask 255.255.255.0
