💡 Even though the article below is targeted specifically at Raspberry Pi OS (formerly called Raspbian) the steps below should work perfectly fine for any Debian based O/S, as well as any other Linux distros which use dhcpcd.
Configuring a static IP address in Raspberry Pi OS is pretty straight forward. To do so we’ll need to disable the default automatic configuration (DHCP) for the network interface in question.
Adding a static configuration
Raspberry Pi OS -like many other Linux distros- uses dhcpcd as its default DHCP client.
The configuration file of dhcpcd is located at
Let’s say you want to use a static IP address of
192.168.0.150, simply add the following lines:
interface eth0 static ip_address=192.168.0.150/24 static routers=192.168.0.1 static domain_name_servers=192.168.0.150 188.8.131.52 184.108.40.206
interface: network interface for which you want to set a static IP (usually
static ip_address: your desired static IP in CIDR notation.
/24refers to netmask
static routers: IP of your router / gateway.
static domain_name_servers: your DNS server(s) of choice. As I’m running a Pi-hole instance on the same device, I’m specifying the same IP followed by Cloudflare’s DNS servers which will serve as a backup should my Pi-hole instance be unreachable.
This is the part you would normally reboot your Raspberry Pi (by running
reboot unsurprisingly 🤷♂️), in order to apply your changes.
Thankfully there is an easier way which doesn’t require a reboot.
Apply changes without rebooting
The command below will bring down the
eth0 interface, ⏸️ pause for exactly 5 seconds and automatically bring it back up afterwards:
sudo ifconfig eth0 down && sleep 5 && sudo ifconfig eth0 up
Verify whether the network interface has been configured by running
... eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 👉 inet 192.168.0.150 netmask 255.255.255.0 broadcast 192.168.0.255 inet6 2a02:1811:c401:4d00:1eb1:5550:706c:b5d prefixlen 64 scopeid 0x0<global> inet6 fe80::df3d:ab2:eb31:e33d prefixlen 64 scopeid 0x20<link> ether dc:a6:32:22:2d:fc txqueuelen 1000 (Ethernet) RX packets 788462 bytes 137882009 (131.4 MiB) RX errors 65535 dropped 65535 overruns 0 frame 0 TX packets 452092 bytes 85263482 (81.3 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 ...
You should now be able to reach your Raspberry Pi using the static IP you configured 👏.
