Static IP Address for Raspbian

Static IP Address

To create a static IP address for Raspbian.

vi /etc/network/interfaces

Change the line

iface eth0 inet dhcp

to

iface eth0 inet static

and add the following lines immediately after the line above otherwise adding the lines to the end of the file will assign the information to the wireless network wlan0.

auto eth0
address 192.168.1.1
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.254

Add an IP Alias

iface eth0:0 inet static
address 192.168.22.1
netmask 255.255.255.0
network 192.168.22.0
broadcast 192.168.22.255
auto eth0:0

Temporary Alias

To create a temporary alias rather than a permanent one you can issue the following command from the CLI.

ifconfig eth0:0 192.168.22.1/24

Bug

As of 3rd June 2015 there is a known bug with Raspbian that always obtains an IP address from DHCP even if a static IP address is configured. This means that the rPi will obtain 2 individual IP address on the NIC. The static been the primary and the DHCP IP been the additional.

To fix this problem if DHCP is not required

apt-get autoremove dhcpcd5

You can also optionally remove

apt-get autoremove isc-dhcp-client isc-dhcp-common
