How do I assign a fixed IP address to my router?

Do you always want to access your network device, for example your NAS or IP camera, via the same address and ultimately also want to access this outside of your network? If so, assign a fixed IP address to the device. You can do this via your router. Do you have a TP-Link, Netgear, or Asus router? If so, you can read how to create a fixed IP address here.

Why do you need a fixed IP address?

You can think of the data transfer between your network devices as a postman delivering his mail. The postman needs a house number to deliver mail, because otherwise he doesn't know if he is at the right address. If a house number keeps changing, the postman must always check what the new number is. Give the house a fixed house number and the postman will always know where to find your house.

Give your devices a fixed IP address so you can always approach them in the same way. You also use a static IP address to access your device remotely if it doesn't have a cloud function.

Before you start

What do you need?

  • A router
  • A laptop or desktop that's connected to the router
  • The device that you want to provide with a fixed IP address (this must also be connected to the router)
  • The MAC address of your device. The MAC address is a unique code that identifies your device. You'll find this out while following the step-by-step plan.

What to keep in mind?

The link with which you can access the configuration page of your router in the step-by-step plan below only works if you're connected to your router's network.

While following the step-by-step plan, look for the MAC address of your device. You recognize the device by brand or type, or by a name that you have given the device. Don't you see anything that looks like your device? If so, take a photo or screenshot of the list. Next, remove the cable from your device and see which one is missing. The one that's missing is the MAC address of your device.

How do I make a screenshot in Windows?

Restart the router and your device after setting up, so the new addresses are copied properly. Bookmark or write down the IP address and attach it to the bottom or back of the device.


  1. Open the user interface of your Netgear router.
  2. Select the 'Advanced' tab at the top of the page. Next, select the 'Install' option on the left side of the menu. A number of choices will appear below your selection, choose 'Set LAN' here.
  3. On the right, you have the DHCP settings. In the section under 'Address reservation', you press 'Add'. A new window will open.
  4. At the top of the page, you'll find an overview of devices. These are the devices that are currently connected to the router. Select your device (for example your printer) by pressing the selection button left in the table.
  5. Choose an IP address for the device in the entry field below the table. Just leave the first 3 sets of digits be. The last set can be adjusted to a number between 1 and 254. It doesn't matter what you choose here, as long as it doesn't overlap with another fixed IP address.
  6. Give your device a name and press 'Add' at the top of the table.
  7. From now on, use the IP address you created to access your device.


  1. Open your browser and go to the configuration page of your Asus router.
  2. Select 'LAN' in the menu on the left. Next, select the 'DHCP Server' tab at the top of the page.
  3. Under your selection, you'll find the DHCP settings. Scroll to the 'Manually Assigned IP around the DHCP list' section.
  4. Click on the arrow next to the entry field under 'MAC address'. Select your device here (for example, your printer).
  5. To the right of the MAC address, you'll find the IP address. Keep the automatically entered value or choose an IP address yourself. Make sure the number matches the 'IP pool'. These are the IP addresses that you can find under the heading 'Basic Config' higher on the page.
  6. Press 'Add'. This is the plus sign.
  7. Choose 'Apply'. Your device can now be accessed via the IP address you just selected.


  1. Open the user interface of your Linksys router.
  2. Select the 'Network assignment' menu in the left navigation bar. You'll get a graphical overview of all connected devices.
  3. Locate the device that you want to provide with a static IP address and click on the name of this device.
  4. Click on 'Reserve DHCP address'. The device is now provided with a fixed IP address.
  5. Do you want to change this IP address? If so, choose Edit DHCP reservation. In the following screen, you can choose the IP address with which you want to access the device.

Access your device

Now that you have given the device a fixed IP address, you can enter this address in your browser to access the configuration page of your device.


Have you created a static IP address to access your network device outside of your network? If so, read the following article to enable this access.
