How to Set Up a Static IP Address

Assign a permanent local IP to a device so it never changes — essential for port forwarding and home servers.

Updated 2026

  1. 1

    Find the device's MAC address

    On Windows run ipconfig /all and note the Physical Address. On a phone, find it in Settings → About → Status.

  2. 2

    Log in to your router

    Open the admin page in your browser.

  3. 3

    Find DHCP reservation or static IP assignment

    Look under LAN, DHCP, or Address Reservation.

  4. 4

    Add a new reservation

    Enter the device's MAC address and the IP you want to assign (e.g. 192.168.1.100). Choose an IP outside the dynamic DHCP range.

  5. 5

    Save and reconnect the device

    Apply the change, then disconnect and reconnect the device to receive the reserved IP.

  6. 6

    Verify the IP

    Run ipconfig (Windows) or check Settings → WiFi on mobile to confirm the assigned address.

Frequently Asked Questions

What's the difference between a static IP and DHCP reservation?
A DHCP reservation assigns the same IP automatically each time the device connects — easier than manually configuring the device's network settings.
Can two devices have the same static IP?
No. Duplicate IPs cause conflicts. Make sure each reservation uses a unique address.
