Many routers allow you to assign a pool of IP addresses that are handed out to specific devices (based on the device’s physical, or MAC address).
This method offers a couple of significant advantages: This article is about assigning static IP addresses directly to PCs running Windows.
For example: Whatever your reason, assigning static IP addresses to devices is not difficult, but you do have a choice to make—whether to do it from the router or on the device itself.
While this article covers assigning static IP addresses to PCs within Windows itself, there is another way to go about it.
Open the Command Prompt and use the command to verify that the changes were successful.
And you can verify your new settings by using the By and large, it’s better to let most of your devices have their IP addresses assigned automatically by your router.
Occasionally, though, you might want to set a static IP address for a particular device.
The downside to automatic addressing is that it’s possible for a device’s IP address to change from time to time.
