장치 인터페이스에 아이피주소를 설정 / 해제

#ip address add 192.168.0.30/24 brd + dev eth0

또는 ifconfig 명령어로 

#ifconfig eth0 192.168.0.30 netmask 255.255.255.0 up

Remove / Delete / Deactivate IP address

#ip address del 192.168.0.30 dev eth0

또는 

#ifconfig eth0 down

Configuration File 에 영구적으로 설정

#vi /etc/network/interfaces

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

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

위는 dhcp 설정을  아래와 같이 설정
#vi /etc/network/interfaces

# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.0.30
netmask 255.255.255.0
gateway 192.168.0.1
