Local static IP vs public static IP
This guide is about your device’s local (private) IP inside your network. A static public IP (the address the internet sees) must be bought from your internet provider.
Method 1 Router: DHCP reservation (recommended)
Phones and laptops may use private MAC addresses; set the device to use a fixed MAC for your network first.
-
Step 1: Open DHCP settings
In your router, look for DHCP Server, LAN, Address Reservation or IP & MAC Binding.
-
Step 2: Pick the device
Select the device from the client list (or enter its MAC address).
-
Step 3: Set an address
Choose an IP (e.g. 192.168.1.50) and save. Restart the device or renew its IP.
Method 2 Windows: manual static IP
-
Step 1: Check current settings
Run ipconfig /all and note the subnet mask, default gateway and DNS.
-
Step 2: Open IP settings
Settings > Network & internet > Wi-Fi (or Ethernet) > Hardware properties > IP assignment > Edit.
-
Step 3: Enter details
Choose Manual, enable IPv4, and enter: IP address (outside the DHCP range), subnet mask 255.255.255.0 (or prefix length 24), gateway (router IP) and preferred DNS. Save.
Troubleshooting
No internet after setting a static IP
Check the gateway and DNS are correct and the IP is in the same subnet (e.g. 192.168.1.x).
“IP address conflict detected”
Another device has that address. Choose a different one or use a reservation.
Frequently asked questions
Why use a static IP?
For port forwarding, printers, NAS drives, servers and cameras that other devices need to find reliably.
Is a static IP more secure?
No. It’s about predictability, not security.
Summary
Use a DHCP reservation in your router for a fixed local IP, or set a manual IP in Windows outside the DHCP range with the right gateway and DNS.
