11.6.2  How to Set up Static IP Address in Raspberry Pi

 

The default setting for the IP address in the Raspberry Pi system is stored in "/etc/network/interfaces" file. Normally, the contents as follows are stored.

 

iface     lo        inet      lookback

iface     eth0     inet      dhcp

iface     wlan0    inet      dhcp

           wpa-ssid                     "wifissid"

           wpa-psk           "wifipassword"

 

To fix IP address in the Raspberry Pi system, you need to modify the contents of the "/etc/network/interfaces" file.

To fix the IP address of wired network, change the contents of the "eth0" adapter. To fix the IP address of wireless network, change the contents of the "wlan0" adapter. Change the DHCP method to "static" for the item to fix IP address, and modify the contents as follows. The following is an example of fixing IP address to a wired network.

 

iface     eth0     inet      static

address           192.168.1.202

netmask            255.255.255.0

gateway            192.168.1.0

 

Specify the desired static IP address for the "address" field, set "255.255.255.0" for the "netmask" field, and specify the IP address of the DHCP server (network server, router) for the "gateway"

After changing the file in this way and rebooting, the Raspberry Pi system is given an IP address of "192.168.1.202".
