How to Set a Static IP Address on Various Operating Systems

Setting a static IP address ensures your server always has the same local network address. This is useful for port forwarding, remote access, and self-hosting.

Ubuntu / Debian (Linux)

1. Edit the netplan config (for Ubuntu 18.04+):

   sudo nano /etc/netplan/01-netcfg.yaml

2. Example static IP config:

   network:
     version: 2 # Netplan config version
     ethernets:
       eth0: # Name of your network interface (may be enp3s0, ens33, etc.)
         dhcp4: no # Disable DHCP (dynamic IP)
         addresses: [192.168.1.100/24] # Set your static IP and subnet (change as needed)
         gateway4: 192.168.1.1 # Your router's IP address
         nameservers:
           addresses: [1.1.1.1,8.8.8.8] # DNS servers (Cloudflare, Google)

3. Apply changes:

   sudo netplan apply

Recommended DNS servers

Cloudflare DNS: 1.1.1.1 / 1.1.0.0

Google DNS: 8.8.8.8 / 8.8.4.4

Windows 10/11

1. Open Settings > Network & Internet > Ethernet (or Wi-Fi).
2. Click your network, then Edit under IP settings.
3. Set to Manual, enable IPv4, and enter your static IP, subnet, gateway, and DNS.

macOS

1. Open System Settings > Network.
2. Select your network interface (Wi-Fi or Ethernet).
3. Click Details (or Advanced), then TCP/IP.
4. Set Configure IPv4 to Manually and enter your static IP, subnet mask, and router.

Router (Recommended for Beginners)

• Many routers let you reserve a static IP for your device (DHCP reservation) via the web interface. This is often easier and avoids OS-level config.
