This guide will show how to setup DHCP or static IP address from command line.
For full details see [the blackmoreops site:](https://www.blackmoreops.com/2015/03/26/setup-dhcp-or-static-ip-address-from-command-line-in-linux/)
1. STOP and START Networking service
`# /etc/init.d/networking stop`
`# /etc/init.d/networking start`
In systems using systemd, then use the following instead:
`# systemctl stop network.service`
`# systemctl start network.service`
2. STOP and START Network-Manager
`# systemctl stop NetworkManager.serviced`
`# systemctl start NetworkManager.serviced`
3. Bring up network interface
`# ifconfig eth0 up`
or
`ifup eth0`
At this point the interface doesn't have an IP address
assigned as can be checked by the following command:
`# ifconfig eth0`
4. Setting up IP Address via DHCP
`# echo "iface eth0 inet dhcp >> /etc/network/interfaces"`
and then bring up the interface as in previous step.
5. Setting up Static IP
`# ifconfig eth0 192.168.43.226`
`# ifconfig eth0 netmask 255.255.255.0`
`# ifconfig eth0 broadcast 192.168.43.255`
` route add default gw 192.168.43.1 eth0`
6. Alternative way of setting up Static IP
`# echo -e “iface eth0 inet dhcp\n address 10.1.1.2\n netmask 255.255.255.0\n gateway 10.1.1.1″>>/etc/network/interfaces`
7. Fix missing Default Gateway
`# ping 8.8.8.8`
8. Setting up Nameserver/DNS
`# echo “nameserver 8.8.8.8\n nameserver 8.8.4.4″ >>/etc/resolv.conf`
