The advantage here is that the process is a little bit more straight-forward, but the downside is that each device might have a different method for assigning a static IP.
Either method will work, so choose whichever option is more convenient.
This article will explain the second method, but only for Windows and OS X.
Note: When assigning a static IP address, be sure you are not choosing an IP that is in the DHCP range, otherwise you might get a message about an IP address conflict, which is what happens when two devices have the same IP address on the network.
Each device on the network has to have a unique IP address.
The IP address for a device may change over time depending on several factors.
This usually doesn’t cause any problem, but there are situations where a static IP address is required.
For example, if your computer is being used as a media server in your home, you might want the IP address to remain the same if you have to connect to the computer via its IP address.
By default, when you type in the IP address, it fills out the subnet mask for you.
The Default gateway and Preferred DNS server should both be set to the IP address of your router.
