Giving your printer a static IP address ensures that your computer always knows the address of your printer as it won’t change if it’s rebooted or if a DHCP IP lease expires. If your printer’s IP address keeps changing, your computer may not always be able to find it. When you print something, your computer and printer locate each other using IP addresses.
But sometimes, you want devices to always have the same IP address.įor example, a wireless printer. Most devices use DHCP, which assigns dynamic IP addresses, as a default. When you use DHCP IP reservation, you're telling your Wi-Fi network to assign the same IP address to a specific device whenever that device connects to your network.
