How to add an IP address to Debian/Ubuntu Linux

 

# sudo vi /etc/network/interfaces

 

Your original will look something like this:

# Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
# /usr/share/doc/ifupdown/examples for more information.

auto lo eth0

iface lo inet loopback

iface eth0 inet static
address XXX.XXX.XXX.XXX
netmask 255.255.255.255
broadcast 0.0.0.0

 

Add the following below it to add another address to the same interface:

auto eth0:1
iface eth0:1 inet static
address XXX.XXX.XXX.XXX
netmask 255.255.255.255
broadcast 0.0.0.0

 

Exit.

# sudo /etc/init.d/networking restart
